The limitation period for a shareholder claim in Ontario is often two years from the date the claim was discovered, but the answer depends on the particular claim and facts. Under the Limitations Act, 2002, discoverability turns on what the claimant knew or reasonably ought to have known.
How Does Ontario’s Two-Year Limitation Period Work?
Section 4 of the Limitations Act, 2002 provides the general rule: unless the legislation provides otherwise, a proceeding cannot be commenced after the second anniversary of the day on which the claim was discovered.
Under s. 5, discovery is based on the earlier of when the claimant actually knew, or a reasonable person in the claimant’s circumstances ought to have known:
- that injury, loss, or damage had occurred;
- that an act or omission caused or contributed to it;
- that the act or omission was attributable to the person against whom the claim is made; and
- that a proceeding would be an appropriate means to seek a remedy.
This makes limitation analysis highly fact-specific. The relevant date may depend on when a shareholder learned of a disputed transaction, exclusion from management, share issuance, diversion of assets, non-payment, corporate decision, or other conduct giving rise to the claim.
Does the Two-Year Period Apply to Oppression Claims?
Yes.
In Maurice v. Alles, the Ontario Court of Appeal confirmed that an oppression claim under the OBCA is subject to the general two-year limitation period.
That is important because an oppression claim does not remain indefinitely available simply because the effects of earlier conduct continue.
For the substantive remedy, see What Is the Oppression Remedy in Ontario?.
What If the Alleged Oppression Continues Over Time?
The distinction between continuing effects and new oppressive acts can be critical.
In Maurice v. Alles, the Court of Appeal held that continuing refusal to provide information did not automatically restart the limitation period. However, a later discrete act that was itself potentially oppressive could create a new claim.
In Zhao v. Li, the Court of Appeal further explained that where there is a series of distinct oppressive acts, some earlier claims may be statute-barred while claims arising from later acts remain timely.
A shareholder therefore should not assume that later conduct revives an older claim or that describing conduct as “ongoing oppression” avoids the limitation period.
Is There Also an Ultimate Limitation Period?
Generally, yes.
Section 15 of the Limitations Act, 2002 establishes a 15-year ultimate limitation period measured from the act or omission on which the claim is based, subject to the statutory rules and exceptions contained in that section.
Different shareholder claims may also involve different statutory provisions, contractual rights, procedural requirements, or limitation issues. The limitation analysis should therefore be performed claim by claim rather than by treating the shareholder dispute as one undifferentiated event.
Where the right belongs to the corporation rather than personally to the shareholder, the procedural route may also differ. See Can a Shareholder Sue Directly in Ontario, or Is a Derivative Action Required?.
How ME Law Approaches Limitation Issues in Shareholder Disputes
ME Law begins by building a chronology of the disputed conduct and identifying each legal claim separately. We review corporate transactions, resolutions, shareholder communications, agreements, financial records, notices, governance changes, and the dates on which the shareholder obtained relevant information.
We then assess when each claim may have been discovered, whether later conduct constitutes a genuinely new actionable event, and whether urgent steps are required to preserve the claim.
Our Shareholder Oppression & Unfair Prejudice Claims practice addresses limitation issues arising within contested shareholder and oppression proceedings.
