What Is a Breach of Fiduciary Duty?
A fiduciary duty is a legal obligation to act in the best interest of another party. It arises in relationships built on trust, such as those between trustees and beneficiaries, directors and shareholders, lawyers and clients, or business partners. A breach of fiduciary duty occurs when the fiduciary puts personal interests ahead of their legal responsibilities, fails to disclose conflicts, or misuses entrusted assets.
Ontario courts take breaches of fiduciary duty seriously and may award significant remedies, including disgorgement of profits, damages, and removal from office.
Common Fiduciary Relationships
Fiduciary duties can arise in many types of relationships, including:
Trustees and Beneficiaries - Trustees must manage assets solely for the benefit of the beneficiaries.
Corporate Directors and Shareholders - Directors must act in the corporation’s best interests, not personal gain.
Business Partners - Partners must disclose conflicts and act honestly with one another.
Legal and Financial Advisors - Professionals owe duties of loyalty, confidentiality, and full disclosure.
Executors and Estate Beneficiaries - Executors must administer the estate fairly and transparently.
Legal Framework for Fiduciary Duties
Ontario fiduciary law is rooted in common law principles and specific statutes. Key duties include:
Duty of Loyalty - The fiduciary must avoid personal gain from the relationship unless fully disclosed and approved.
Duty of Honesty - Fiduciaries must act with utmost good faith and disclose relevant information.
Duty of Care - They must act diligently and competently in performing their obligations.
Conflict of Interest - Fiduciaries must avoid situations where their interests conflict with their duties.
No Secret Profits - Any benefit gained from the role must be surrendered to the rightful beneficiary or principal.
Challenges in Breach of Fiduciary Duty Claims
These cases often involve complex evidence and emotional disputes. Common challenges include:
Proving the Duty - The claimant must establish that a fiduciary relationship existed.
Proving the Breach - Showing the fiduciary acted in self-interest, concealed information, or failed in their duties.
Quantifying Damages - Determining what losses or unjust gains resulted from the breach.
Corporate Complexity - In business settings, roles and obligations may be blurred or undocumented.
Statutory and Common Law Overlap - Navigating overlapping legal sources requires precise legal interpretation.
