Statute of Limitations in Canada by Province

A limitation period is the deadline for starting a lawsuit. Miss it, and a claim that might otherwise have succeeded is usually barred forever, regardless of how strong the underlying facts are. In Canada, limitation law is set at the provincial and territorial level rather than federally, so the deadline for the same type of claim can differ depending on where the events occurred.

This guide compares the basic limitation periods across Canada's provinces and territories, explains the discoverability rule that decides when the clock actually starts, and flags the claim types, such as sexual assault or consumer debt, that follow special rules. For broader context on your rights as a consumer, see Canada consumer protection.

What a Limitation Period Does

A limitation period, called a prescription period in Quebec's civil law system, is the maximum time the law allows someone to start a court proceeding after a legal wrong occurs. It exists to give both sides certainty, to encourage people to pursue claims while evidence and memories are still fresh, and to protect defendants from having to answer very old claims.

Once the applicable limitation period runs out, the claim is generally statute barred. That does not erase the underlying dispute, but it gives the defendant a complete legal defence, and a court will typically dismiss the claim on that basis alone, without weighing whether it would otherwise have succeeded.

Limitation Law Is Set by Each Province

Unlike criminal law, which is federal across Canada, the law governing civil lawsuits, including limitation periods, is provincial and territorial. Each province and territory has its own Limitations Act, Limitation Act, or Limitation of Actions Act, and Quebec instead uses the Civil Code of Quebec.

That means the deadline for the same type of dispute, for example a breach of contract or a car accident claim, can differ depending on where you live or where the events took place. Most of English Canada has moved to a similar discovery based model over the past two decades, but Quebec, Prince Edward Island and the northern territories still work somewhat differently, as explained below.

The Discoverability Rule

Most provinces do not start the limitation clock on the date something harmful happened. Instead, they apply discoverability: the clock starts on the day the claimant knew, or reasonably ought to have known, that the injury, loss or damage occurred, that it was caused by an act or omission, and that the act or omission was that of the person being sued.

This matters most for harm that is not obvious right away, such as a construction defect discovered years after a building was completed, or a health complication that only becomes apparent once a condition worsens. In those cases, the basic limitation period can start well after the underlying event took place, though the ultimate limitation period described below still eventually cuts the claim off.

Basic and Ultimate Limitation Periods by Province

The table below summarizes the general civil limitation periods for each province and territory. It covers ordinary civil claims such as contract and negligence disputes; specific claim types, including debt, real property, family law and sexual assault, can follow different periods, described further down. Always confirm the period that applies to your specific claim against the relevant statute, since legislatures amend these laws from time to time.

A Note on Quebec

Quebec is a civil law jurisdiction, and the applicable concept is prescription rather than limitation. Under the Civil Code of Quebec, the general prescriptive period for personal actions, including most contract and civil liability claims, is 3 years from the day the damage first appeared. Defamation claims carry their own shorter period of 1 year, running from the day the defamed person learned of the defamatory statement.

Because Quebec's civil code works differently from the common law model used elsewhere in Canada, do not assume a period taken from an Ontario or British Columbia case applies there. Confirm the specific article of the Civil Code that governs your claim.

A Note on Prince Edward Island and the Territories

Prince Edward Island, Yukon, the Northwest Territories and Nunavut have not adopted the newer basic-plus-ultimate model used across most of the rest of Canada. Instead, their statutes list specific periods for specific claim types, for example one length for debt actions, another for defamation, another for actions on a judgment, with a general catch-all period for anything not separately listed.

That structure makes it harder to give one number that covers every claim. If your claim arose in one of these jurisdictions, confirm the exact period against the relevant section of that province or territory's Limitations Act or Limitation of Actions Act, since the answer depends heavily on the type of claim involved.

Special and Extended Limitation Periods

Certain categories of claims follow rules that differ from the general periods in the table above:

• Minors and mental incapacity: limitation periods are generally suspended while a claimant is a minor or lacks the mental capacity to manage their affairs, typically starting only once that disability ends.
• Sexual assault and sexual misconduct: every Canadian province and territory has eliminated the limitation period for claims based on sexual assault, and for related misconduct where the claimant was a minor or the relationship involved a position of trust, authority or dependency. These claims can generally be started at any time.
• Consumer debt: unpaid debts such as credit cards and loans generally follow the basic limitation period in the table above, and a written acknowledgment of the debt or a partial payment can restart the clock. See debt collection rules for how this plays out with collection agencies, and what can follow once a creditor obtains a judgment, including wage garnishment in Canada.
• Real property and judgments: claims to recover land, and actions to enforce a court judgment, commonly carry longer periods, often 10 years or more, set out separately in each province's statute.
• Government and municipal claims: many provinces require a short notice period, sometimes as little as 10 to 60 days, before suing a municipality or public authority, on top of the ordinary limitation period. Missing that notice deadline can bar a claim even within the general limitation period.

What Happens If You Miss the Deadline

If a limitation period has expired, the defendant can raise it as a defence, and a court will typically dismiss the claim on that basis alone, without weighing the merits. Courts apply limitation periods strictly, since the purpose of the rule is to create certainty and finality for both sides.

There are narrow exceptions in some provinces, such as postponement during active settlement negotiations, fraudulent concealment by the defendant, or limited court discretion in specific personal injury circumstances, but these are the exception rather than something to plan around. The safer approach is always to act well before the deadline.

Protecting Your Right to Sue

If you think you may have a claim, note the date you first learned of the harm and who may be responsible, since that date often starts the clock under the discoverability rule. Gather documents, photos, receipts and correspondence early, before they are lost or become harder to obtain.

Getting legal advice promptly, rather than close to a suspected deadline, gives a lawyer time to confirm which limitation period applies, since that can depend on the type of claim, the province involved, and sometimes more than one statute. For how provincial law varies across the country more broadly, see Canadian law by province.

Disclaimer

This article provides general information about limitation periods across Canada and is not legal advice. Limitation periods are fact specific, depend on the exact type of claim and the province or territory involved, and can be affected by exceptions this article does not cover. If you believe you may have a claim, consult a lawyer licensed in the relevant province or territory promptly, since waiting can cost you the right to sue regardless of the merits of your case.
