Corporate & Commercial Litigation in Ontario: Common Disputes and Legal Strategies

In Ontario’s business landscape, corporate and commercial disputes often determine the survival, control, and future trajectory of a company. Whether arising from shareholder conflicts, broken contracts, or allegations of fiduciary breach, these disputes cut to the core of corporate relationships and financial stability.

Unlike simple private disagreements, corporate litigation operates within a sophisticated framework of statutes, precedents, and equitable doctrines designed to uphold fairness, transparency, and accountability in commerce. The Ontario Business Corporations Act (“OBCA”), Canada Business Corporations Act (“CBCA”), and common law principles govern how partners, directors, and companies must conduct themselves—and what remedies are available when they do not.

This guide provides an in-depth overview of the six most common categories of corporate and commercial litigation in Ontario, each illustrated by leading cases and practical strategies:

1. Shareholder & Partnership Disputes – Deadlock, oppression, and fiduciary breach.
2. Contractual Disputes – Breach, misrepresentation, and good faith obligations.
3. Commercial Real Estate & Leasing – Complex transactions and co-ownership conflicts.
4. Corporate Governance & Director Liability – Fiduciary duties and accountability.
5. Business Sale & M&A Litigation – Share purchase disputes and valuation controversies.
6. Fraud, Misrepresentation & Asset Recovery – Tracing, freezing, and recovering corporate assets.

At ME Law Professional Corporation, our litigators act for business owners, investors, and corporations across Ontario—resolving disputes strategically and decisively. Whether through negotiation, mediation, or aggressive courtroom advocacy, our mission is to protect value, preserve control, and achieve outcomes that serve our clients’ long-term commercial interests.

Introduction: Why Corporate & Commercial Litigation Matters

Business relationships are built on trust—but sustained through enforceable obligations. When those obligations are breached, ignored, or manipulated, the consequences can be existential.

From two partners in a growing start-up to a mid-size company negotiating a merger, commercial relationships often involve significant investments of capital, labour, and goodwill. Disputes over ownership, performance, or misrepresentation can destabilize an entire enterprise if left unchecked.

Consider these common scenarios:

• A minority shareholder is excluded from company management and dividends while majority owners siphon profits to related entities.
• A supplier fails to deliver critical components, causing the buyer’s operations to halt and reputation to suffer.
• A commercial tenant is locked out of its premises due to a disputed rent increase clause.
• A director diverts a lucrative opportunity to a competitor they secretly control.
• A purchaser of a business later discovers financial misrepresentations concealed during the sale.
• A trusted employee embezzles funds and hides the transactions through accounting manipulation.

Each example touches on a distinct but interrelated branch of commercial law—and each requires a rapid, strategic legal response to protect assets, evidence, and control.

Corporate and commercial litigation is not merely about compensation; it is about preserving enterprise value and ensuring fairness in the marketplace. Courts in Ontario recognize that when fiduciaries or contracting parties breach their obligations, the ripple effects extend far beyond balance sheets.

The following sections unpack the six pillars of Ontario’s corporate and commercial litigation framework, drawing from foundational jurisprudence and real-world examples.

1. Shareholder & Partnership Disputes

Few disputes are as disruptive—or as personal—as those arising between shareholders or partners. At their core, these cases are about trust, control, and fairness within closely held businesses.

Ontario courts have developed a sophisticated body of law to balance entrepreneurial freedom with equitable protection. The cornerstone of this area is the oppression remedy under section 248 of the OBCA, mirrored in section 241 of the CBCA.

The Oppression Remedy: Protecting Fair Expectations

The leading case, BCE Inc. v. 1976 Debentureholders, 2008 SCC 69, remains the Supreme Court’s definitive statement on the oppression remedy. The Court emphasized that corporate decisions must respect the “reasonable expectations” of stakeholders and not unfairly disregard or prejudice their interests.

In practice, this remedy provides a flexible, equitable shield for minority shareholders against majority abuse. Conduct may be “oppressive” even if technically lawful—such as when controlling shareholders:

• Exclude minorities from management or financial information;
• Dilute their ownership through unfair share issuances;
• Divert corporate opportunities to themselves;
• Pay themselves excessive salaries while withholding dividends.

Remedies can include damages, share buyouts, reversal of transactions, or even appointment of an independent director or receiver.

Partnership and Joint Venture Deadlock

In partnerships or 50/50 corporations, deadlock can paralyze operations. Courts have broad discretion to dissolve partnerships or order one party to buy out the other under the Partnerships Act or equitable principles.

In Robak Industries Ltd. v. Gardner, 2007 ONCA 793, the Court of Appeal confirmed that courts will intervene when partners can no longer act in mutual trust or good faith. The same logic applies to incorporated joint ventures where governance breakdown renders the business unworkable.

Fiduciary Duties and Misuse of Corporate Opportunity

Directors, officers, and sometimes even controlling shareholders owe fiduciary duties to act honestly and in the best interests of the corporation. The Supreme Court in Peoples Department Stores Inc. v. Wise, 2004 SCC 68, and BCE, clarified that these duties focus on the corporation itself—not on personal or factional gain.

When insiders divert corporate opportunities or compete unfairly, Ontario courts often impose constructive trusts or accounting of profits to ensure that ill-gotten gains revert to the corporation.

Valuation and Buy-Sell Disputes

Disputes over share valuation—particularly under shotgun or buy-sell clauses—can become litigious when parties disagree on fair market value or accounting methods. Courts enforce these clauses strictly but intervene where bad faith or manipulation occurs.

In Mancuso v. Capriotti, 2015 ONSC 7310, the Court scrutinized a shotgun buyout initiated in bad faith to exploit an undervalued offer. The decision reaffirmed that contractual rights must be exercised honestly and consistent with reasonable expectations.

Practical Takeaways for Businesses

• Draft clear shareholder agreements setting out buyout rights, decision thresholds, and dispute resolution processes.
• Maintain transparent financial reporting to avoid claims of exclusion or oppression.
• Document all decisions to show compliance with fiduciary and statutory duties.
• Seek early legal advice—injunctions may prevent share transfers or asset dissipation during disputes.

At ME Law, we regularly act for both majority and minority shareholders in Ontario corporations. Our focus is preserving enterprise value while enforcing fairness and accountability through strategic, decisive litigation.

2. Contractual Disputes

Contracts are the backbone of commerce. Every corporate relationship—from supply and distribution to employment, consulting, or financing—depends on mutual performance and honest dealing. When one side fails to deliver, the resulting breach can disrupt entire business operations.

Ontario’s courts interpret contracts through both black-letter law and the modern duty of good faith—ensuring that commercial parties not only follow the letter of their agreements but also act with integrity and fairness.

The Duty of Good Faith and Honest Performance

The Supreme Court’s landmark decision in Bhasin v. Hrynew, 2014 SCC 71, revolutionized Canadian contract law by recognizing an “organizing principle of good faith.” Parties must perform contracts honestly and not mislead one another about matters directly linked to performance.

Later cases extended and refined this principle:

• Callow v. Zollinger, 2020 SCC 45 – A condominium corporation was found liable for misleading silence after failing to correct a contractor’s mistaken belief that a renewal was forthcoming.
• Wastech v. Metro Vancouver, 2021 SCC 7 – Confirmed that discretionary contractual powers must be exercised reasonably and in alignment with the parties’ bargain.

Together, these cases transformed the landscape of commercial litigation. Even when a contract grants wide discretion, the exercise of that discretion must not defeat the contract’s purpose or intentionally mislead the counter-party.

Common Types of Contractual Disputes

1. Breach of Supply or Service Agreements
   Disputes often arise when one party delivers defective products, delays performance, or fails to meet quality standards. Ontario courts typically award damages based on the “expectation interest”—putting the innocent party in the position they would have been in had the contract been performed.
2. Termination for Cause vs. Convenience
   Whether a party can unilaterally terminate depends on the precise wording of the termination clause. In M.J.B. Enterprises v. Defence Construction (1951) Ltd., 1999 SCC 29, the Court emphasized that clear contractual terms govern, but they will be interpreted narrowly when invoked opportunistically.
3. Misrepresentation and Rescission
   If a contract was induced by false statements—whether fraudulent, negligent, or innocent—the injured party may seek rescission (undoing the deal) or damages. The courts look closely at the degree of reliance and whether the misrepresentation was material.
4. Frustration and Force Majeure
   Where unforeseen events make performance impossible or radically different, the doctrine of frustration may apply. During the pandemic, Ontario courts examined whether COVID-19 constituted frustration; results varied based on contract wording and foreseeability. Force majeure clauses—contractual frustration clauses—are strictly construed, as shown in Atcor Ltd. v. Continental Energy Marketing Ltd.
5. Indemnity and Limitation of Liability
   These clauses allocate risk but are not absolute. Courts require precise drafting and will not enforce provisions that exclude liability for fraud, intentional misconduct, or fundamental breach.

Strategic Considerations in Contract Litigation

Corporate clients must approach contract disputes with both speed and documentation. The earliest correspondence—emails, invoices, meeting notes—often decides outcomes.

• Mitigate losses immediately. Courts expect reasonable efforts to reduce damages.
• Preserve evidence—document deficiencies, record conversations, and avoid inflammatory correspondence.
• Engage counsel early if termination or non-performance is contemplated; pre-litigation missteps often shape the narrative that reaches court.
• Consider interim remedies. Where ongoing harm threatens a business (e.g., non-delivery of critical materials), injunctions under the RJR-MacDonald test may stabilize the situation pending trial.

At ME Law, our litigators help clients navigate these high-stakes disputes from the first breach notice to final judgment—aligning legal strategy with commercial reality.

3. Commercial Real Estate & Leasing

Real estate is a fundamental corporate asset class—and often the single largest line item on a company’s balance sheet. Commercial property transactions and leases combine legal, financial, and operational complexities. When disputes arise, they can disrupt entire enterprises or investment portfolios.

Breach of Agreement of Purchase and Sale

In Ontario, the sale of land is treated as unique. While damages may compensate monetary loss, the court may grant specific performance when the property has distinctive qualities or strategic value to the purchaser.

In Semelhago v. Paramadevan, 1996 SCC 2, the Supreme Court clarified that specific performance is not automatic but remains available where the land’s uniqueness makes damages inadequate.

Further, in Southcott Estates v. Toronto Catholic District School Board, 2012 SCC 51, the Court denied specific performance because the plaintiff failed to mitigate by pursuing comparable properties. The message was clear: even in real estate disputes, commercial prudence matters.

Co-Ownership and Development Disputes

When multiple investors or partners co-own commercial property, disagreements over financing, development timelines, or sale can trigger litigation under Ontario’s Partition Act. Courts may order sale, division, or appointment of a trustee for sale where continued co-ownership is untenable.

These disputes often intersect with partnership or shareholder claims—particularly when the property is held through a corporation or joint venture vehicle.

Commercial Leasing Conflicts

Commercial lease disputes are among the most frequent forms of business litigation. They can involve:

• Rent arrears and default remedies
• Maintenance and repair obligations
• Renewal and termination rights
• Assignment and subletting disputes
• Enforcement of personal guarantees

Ontario courts interpret lease provisions strictly, but equitable relief may be available to tenants under section 20 of the Commercial Tenancies Act where forfeiture would cause disproportionate hardship.

In Ontario (Attorney General) v. 1236072 Ontario Inc., 2009 ONCA 308, the Court of Appeal reaffirmed that relief from forfeiture depends on prompt payment and bona fide intent to perform going forward.

Property Manager and Developer Disputes

When developers or property managers breach fiduciary or contractual obligations—such as misallocating funds or engaging in self-dealing—courts may impose constructive trusts or order accounting of profits.

The case Soulos v. Korkontzilas, 1997 SCC 4, remains foundational: a real estate agent who improperly acquired property intended for a client was compelled to transfer it back under a constructive trust. The principle applies broadly to fiduciaries in real estate contexts.

Certificates of Pending Litigation (CPLs)

CPLs are potent tools for protecting property interests during litigation. They effectively “freeze” title, preventing sale or mortgage until the dispute is resolved. However, as the Ontario Superior Court noted in Perruzza v. Spatone, 2010 ONSC 841, CPLs are discretionary and must balance fairness against a defendant’s right to freely deal with their property.

Strategic misuse of a CPL can backfire; courts may discharge it and award costs if the underlying claim lacks merit.

Practical Guidance for Corporate Clients

• Document all communications during negotiations or lease performance.
• Act quickly—injunctive relief or a CPL may be necessary to preserve rights.
• Beware of self-help remedies. Lockouts or unilateral terminations can invite damages or reinstatement orders.
• Engage litigation counsel early when property forms part of a broader commercial conflict.

At ME Law, we help investors, landlords, tenants, and developers protect their interests in real estate disputes. From securing title to enforcing agreements of purchase and sale, we combine deep legal insight with commercial pragmatism.

4. Corporate Governance & Director Liability

Good corporate governance is the foundation of trust between shareholders, management, and the public. It is also one of the most litigated areas of modern commercial law. When directors or officers fail to act with integrity, diligence, and transparency, the resulting losses—financial and reputational—can devastate companies and stakeholders alike.

Fiduciary Duties and the Standard of Care

Under both the OBCA and CBCA, directors and officers must:

1. Act honestly and in good faith with a view to the best interests of the corporation, and
2. Exercise the care, diligence, and skill that a reasonably prudent person would exercise in comparable circumstances.

These dual obligations—fiduciary loyalty and due care—were explored extensively in Peoples Department Stores Inc. v. Wise, 2004 SCC 68, and reaffirmed in BCE Inc. v. 1976 Debentureholders, 2008 SCC 69.

The Supreme Court emphasized that fiduciary duties are owed to the corporation itself, not to any particular stakeholder group. This distinction prevents directors from prioritizing shareholders, creditors, or employees at the expense of the company’s long-term interests.

The business judgment rule further protects directors from hindsight criticism: courts will not second-guess honest, informed, and reasonable business decisions made in good faith, even if the outcome proves unsuccessful.

Conflict of Interest and Related-Party Transactions

Directors must avoid situations where personal interests conflict with corporate duties. Section 132 of the OBCA requires full disclosure of material interests and abstention from voting on related-party matters.

Courts strictly enforce these obligations. In Canadian Aero Service Ltd. v. O’Malley, [1974] SCR 592, senior officers who appropriated a corporate opportunity for personal gain were found in breach of fiduciary duty and required to disgorge profits. This principle remains the cornerstone of Canadian corporate accountability.

Corporate Record-Keeping, Audit, and Disclosure

Accurate record-keeping is not a procedural formality—it is a legal obligation. Inadequate corporate records can lead to fines, adverse inferences, and even piercing of the corporate veil.

Litigation often arises when shareholders allege mismanagement or concealment of financial information. Courts may compel production of records, appoint an inspector under section 161 of the OBCA, or, in extreme cases, order the removal of directors.

In R. v. Kelly, [1992] OJ No. 1033 (Gen. Div.), the court underscored that failure to maintain proper accounting records can constitute evidence of fraud or breach of statutory duty.

Misrepresentation in Financial Disclosure

Public and private companies alike may face claims for misrepresentation—whether in financial statements, offering memoranda, or investor communications. Plaintiffs may pursue statutory claims under securities legislation or common law actions for negligent misrepresentation.

The case Hercules Managements Ltd. v. Ernst & Young, [1997] 2 SCR 165, remains seminal. The Supreme Court held that auditors owe duties of care to shareholders in certain contexts but not to the public at large, drawing a careful boundary around professional liability.

Practical Guidance for Corporate Officers and Boards

• Disclose early and completely. Hidden conflicts are often more damaging than disclosed ones.
• Document board decisions comprehensively to invoke the protection of the business judgment rule.
• Engage independent legal and financial advice when conflicts or major transactions arise.
• Respond promptly to shareholder inquiries—silence often fuels oppression claims.

At ME Law, we assist directors, officers, and corporations in navigating governance disputes, defending fiduciary claims, and implementing policies that prevent litigation before it starts. Our goal is to protect both the enterprise and the individuals who lead it.

5. Business Sale & M&A Litigation

The sale or acquisition of a business is one of the most complex and consequential transactions in commerce. When things go wrong—whether due to misrepresentation, valuation disagreements, or breaches of closing conditions—the resulting litigation can involve millions of dollars and years of operational disruption.

Ontario courts approach M&A disputes through a blend of contract law, equity, and commercial reasonableness, emphasizing both precision in drafting and fairness in execution.

Share Purchase Agreement (SPA) Breaches

Most M&A disputes arise under Share Purchase Agreements (SPAs) or Asset Purchase Agreements (APAs). Common breaches include:

• Failure to disclose liabilities or pending litigation;
• Breach of representations and warranties;
• Non-payment or adjustment of purchase price;
• Violation of non-compete or confidentiality clauses.

Because SPAs are highly negotiated, courts interpret them based on their wording, context, and the parties’ conduct. In Sattva Capital Corp. v. Creston Moly Corp., 2014 SCC 53, the Supreme Court confirmed that contractual interpretation is a question of mixed fact and law—emphasizing the “factual matrix” over purely textual analysis.

This modern approach allows courts to consider commercial context—such as pre-contract conduct and business purpose—when determining whether a breach occurred.

Earn-Out and Valuation Disputes

Earn-out provisions link additional payments to future performance metrics. These clauses are fertile ground for litigation when sellers allege that buyers deliberately depressed post-closing performance to avoid payouts.

Courts have held that purchasers must act honestly and in good faith in managing the acquired business during the earn-out period. The logic of Bhasin v. Hrynew and Callow v. Zollinger applies directly: even if the contract grants discretion, that discretion must be exercised reasonably and without deception.

Fraudulent Misrepresentation and Concealment

M&A transactions are particularly vulnerable to misrepresentation—whether intentional (fraudulent) or negligent. Sellers may misstate earnings, hide tax liabilities, or fail to disclose regulatory risks.

In Wang v. Shao, 2019 BCCA 130, the court found a seller liable for failing to disclose material information that would have influenced the buyer’s decision to purchase property. Though not an Ontario case, the principles apply across jurisdictions: full and honest disclosure is mandatory when material facts are known exclusively to one side.

Breach of Confidentiality and Non-Solicitation Clauses

Non-solicitation and confidentiality provisions are standard in M&A deals, but enforcement requires careful drafting. Ontario courts enforce such clauses if they are reasonable in scope, duration, and geography. Overly broad restrictions may be struck down as contrary to public policy.

In Payette v. Guay Inc., 2013 SCC 45, the Supreme Court upheld restrictive covenants linked to a business sale, distinguishing them from employment contracts where stricter scrutiny applies.

Disputes Over Closing Conditions and Escrow Funds

Closing conditions—such as financing approval, regulatory clearance, or satisfactory due diligence—often become flashpoints when one party refuses to close. Courts analyze whether the condition was genuinely unmet or invoked opportunistically to escape a declining deal.

Escrow disputes arise when funds are withheld post-closing pending verification of representations. In these cases, precision in the escrow agreement is critical; vague conditions invite costly litigation.

Practical Strategies for Corporate Clients

• Conduct rigorous due diligence—financial, legal, and operational—before signing.
• Document negotiations to preserve context for future interpretation.
• Include clear dispute resolution mechanisms, such as arbitration or expert determination for valuation disputes.
• Engage independent counsel to ensure fairness and enforceability of restrictive covenants.
• Act promptly if misrepresentation or non-performance is suspected; delay may waive remedies.

At ME Law, we represent both buyers and sellers in post-closing litigation and negotiation. Our approach is pragmatic and commercial—focused on salvaging value and resolving disputes with minimal disruption to ongoing operations.

6. Fraud, Misrepresentation & Asset Recovery

Fraud remains one of the most serious and disruptive events a business can face. Whether perpetrated by insiders, counterparties, or third parties, commercial fraud erodes trust and can devastate financial stability. Ontario’s courts have developed a powerful suite of equitable and procedural tools to trace, freeze, and recover misappropriated assets before they vanish.

Corporate Fraud and Embezzlement

Fraud takes many forms: falsified invoices, diverted receivables, fake suppliers, or misappropriation of company funds. Corporate insiders—officers, employees, or partners—may conceal misconduct through accounting manipulation or shell entities.

Ontario courts treat fiduciary and employee fraud as both civil and equitable wrongs. Victims may pursue parallel civil recovery and criminal complaints. Civil remedies often move faster and target restitution, including tracing assets into bank accounts or property holdings.

Accounting Manipulation and False Invoicing

Fraudulent accounting can distort financial statements, affect valuation, and mislead investors or creditors. Civil actions may allege deceit, breach of fiduciary duty, or negligent misrepresentation. The test for fraud, articulated in Bruno Appliance and Furniture Inc. v. Hryniak, 2014 SCC 8, requires proof of false representation, knowledge of falsity, intent to deceive, reliance, and resulting loss.

In many cases, forensic accountants play a key role in reconstructing records, identifying missing funds, and establishing the factual matrix necessary for recovery.

Misappropriation of Trade Secrets and Confidential Information

Beyond money, corporate fraud frequently involves misuse of information. Employees or partners may steal client lists, pricing models, or intellectual property to benefit competitors. Courts routinely issue injunctions, Anton Piller orders, or damages for breach of confidence and conversion.

The leading case, Cadbury Schweppes Inc. v. FBI Foods Ltd., [1999] 1 SCR 142, confirmed that misuse of confidential information can ground liability even without a formal contract, so long as the defendant knew or should have known the information was confidential.

Asset Tracing and Recovery

The goal of asset recovery litigation is to prevent wrongdoers from profiting or hiding stolen value. Remedies include:

• Mareva Injunctions – Freezing assets before judgment to prevent dissipation (as established in Aetna Financial Services Ltd. v. Feigelman, [1985] 1 SCR 2).
• Norwich Orders – Compelling banks or third parties to disclose information identifying wrongdoers or tracing funds.
• Constructive Trusts – Imposing equitable ownership where assets were obtained through breach of duty or unjust enrichment (Soulos v. Korkontzilas, [1997] 2 SCR 217).
• Accounting of Profits – Requiring disgorgement of ill-gotten gains.

Together, these remedies form a sophisticated toolkit enabling litigators to act swiftly and decisively when fraud is suspected.

Professional Negligence and Third-Party Accountability

Sometimes, corporate fraud succeeds because auditors, accountants, or advisors fail to detect it. Victims may sue for professional negligence or breach of duty of care, as recognized in Hercules Managements Ltd. v. Ernst & Young. Courts balance foreseeability, reliance, and public policy to determine the scope of professional liability.

Practical Strategies for Clients Facing Fraud

• Move quickly—delay allows assets to dissipate or be transferred offshore.
• Preserve and secure digital and physical evidence.
• Engage forensic accountants early.
• Consider injunctions, tracing orders, or urgent motions ex parte.
• Coordinate civil recovery with any parallel criminal or regulatory process.

At ME Law, we combine litigation, forensic, and recovery expertise to pursue complex fraud cases. Our team acts swiftly to secure injunctions, trace funds, and recover stolen or diverted assets before they disappear.

The Role of Litigators in Corporate Disputes

Corporate litigation is as much about prevention as resolution. Effective counsel anticipate conflicts, negotiate settlements strategically, and act decisively when formal proceedings become necessary.

At ME Law, our litigators serve as both advisors and advocates through four key functions:

1. Risk Prevention

• Reviewing shareholder, partnership, and commercial agreements and making sure that appropriate dispute-prevention clauses are intact.
• Advising directors on compliance, governance, and fiduciary duties.
• Auditing existing contracts for exposure and ambiguity.

2. Dispute Resolution

• Using mediation and arbitration to reach efficient outcomes.
• Negotiating buyouts or restructurings to preserve business continuity.
• Preventing escalation through early, strategic communication.

3. Courtroom Advocacy

• Litigating injunctions, shareholder oppression claims, and complex contract disputes.
• Applying for asset-freezing or evidence-preserving orders.
• Presenting clear, persuasive arguments rooted in evidence and equity.

4. Strategic Protection

• Anticipating opponent tactics and pre-empting harmful actions.
• Coordinating with accountants, valuators, and investigators.
• Ensuring that legal remedies align with long-term business objectives.

The Litigation Process in Ontario

Corporate litigation follows the same procedural framework as other civil matters under the Rules of Civil Procedure (R.R.O. 1990, Reg. 194), but the scale and complexity of evidence often differ. The major stages are:

1. Pleadings – Filing of Statements of Claim and Defence outlining issues and remedies.
2. Motions – Interim relief such as injunctions, document production, or dismissal.
3. Discovery – Exchange of evidence, including financial records and examinations under oath.
4. Mediation – Mandatory in many Ontario jurisdictions before trial.
5. Trial – Judicial determination of remaining disputes.
6. Appeal – Review by higher courts for legal or procedural error.

Throughout these stages, timing, documentation, and strategy are paramount. Poorly drafted pleadings or late disclosure can undermine even strong cases.

Remedies in Commercial Disputes

Courts possess wide discretion to craft remedies tailored to each case’s realities. Common examples include:

• Damages: Compensation for losses from breach or negligence.
• Equitable Remedies: Mareva injunctions, constructive trusts, and specific performance.
• Buyouts and Dissolution: For shareholder oppression or partnership breakdowns.
• Declaratory Relief: Judicial clarification of contractual or corporate rights.
• Restitution and Accounting: Repayment or disgorgement of benefits gained through wrongdoing.
• Costs Awards: Reimbursement of legal expenses where warranted by fairness or misconduct.

Case Studies and Illustrations

A turning point in Canadian contract law, Bhasin established that honesty and good faith are implied duties in every contract, reshaping how commercial parties must behave.

Real Estate Litigation – Southcott Estates v. TCDSB
The Supreme Court ruled that failure to mitigate can bar equitable relief. Even sophisticated plaintiffs must act pragmatically in commercial contexts.

Director Misconduct – Canadian Aero Service Ltd. v. O’Malley
The Court imposed liability on executives who usurped a corporate opportunity, cementing fiduciary responsibility as a core governance principle.

Fraud and Asset Recovery – Aetna v. Feigelman
The Court’s recognition of Mareva injunctions gave Canadian litigants a critical tool to preserve assets pending judgment.

FAQ

Can a minority shareholder force a buyout?
Yes. Under section 248 of the OBCA, courts can compel a fair-value purchase if oppression or unfair prejudice is proven.

What if a contract partner acts dishonestly but technically follows the contract?
Good faith and honesty obligations, established in Bhasin and Callow, require truthful, non-misleading performance even within strict wording.

Can assets be frozen before trial?
Yes. A Mareva injunction may freeze bank accounts or property when there’s credible evidence of dissipation risk.

Are directors personally liable for corporate debts?
Generally no, unless they commit fraud, breach fiduciary duty, or contravene specific statutory provisions (e.g., unpaid wages, taxes).

Can courts unwind a business sale?
In rare cases involving fraud or material misrepresentation, courts may rescind the transaction or order restitution.
