Amending a Pleading:
Changes Following Expiry of the Limitation Period
Last Updated: July 03 2026
Question: Can I amend my statement of claim in Ontario after the limitation period has expired, and what makes the amendment impermissible or permissible?
Answer: Freed Legal Services can help you assess whether your proposed amendment to a pleading after a limitation period in Ontario will be treated as a permissible clarification or an impermissible new cause of action, based on whether the original pleading already included the necessary material facts and whether the amendment fits the “same factual matrix.” In Kanhai v. Toronto Transit Commission, 2024 ONSC 3986, the court confirmed that where the original claim pleads substantially all material facts giving rise to the further remedies, an amendment that seeks additional forms of relief or an alternative remedy flowing from those facts is not a new cause of action, including guidance from Klassen v. Beausoleil, 2019 ONCA 407, and Di Filippo v. Bank of Nova Scotia, 2024 ONCA 33 about asserting another legal basis for a remedy arising out of the same facts (rather than being time-barred because of the particular legal basis). If your amendment tries to advance a fundamentally different claim on facts you did not plead within the limitation period, it will generally be refused, so it is important to review exactly what facts were in your original pleading before you file.

Amending Pleadings After Limitation Period Expiration
The amendment of a pleading after the expiration of the limitation period remains a significant issue within litigative proceedings. Such amendments often involve adding new causes of action, proposing additional legal theories, or modifying damages claims, whereas all such amendments are dependent upon previously pleaded material facts; and accordingly, amendments that are for a purpose other than the stating of previously omitted material facts are, generally, permissible and will be allowed by the court. Amendments seeking to add material facts that were omitted from pleadings raised during the limitation period will, generally, be forbidden.
The Law
The case of Kanhai v. Toronto Transit Commission, 2024 ONSC 3986, provides insightful guidance into what constitutes as a proper and permissible amendment to a pleading following the expiration of a relevant limitation period. Specifically, in the Kanhai case, it was said:
[7] Where a claim already pleads substantially all of the material facts that give rise to the further proposed remedies, amendments that set out an alternative claim for relief arising out of the same general factual matrix previously pleaded are not a new cause of action. (Galluzzi v Pearlann Consulting Inc. 2017 ONSC 3298 at paragraph 9). I note the language of the “same factual matrix” was specifically referenced by the HRTO in its decision dismissing the plaintiff’s application, reproduced at paragraph 5, infra.
[8] This motion to amend the statement of claim is on all fours with Klassen v Beausoleil 2019 ONCA 407 which held at paragraph 28:
An amendment does not assert a new cause of action - and therefore is not impermissibly statute-barred - if the “original pleading contains all the facts necessary to support the amendments ... such that the amendments simply claim additional forms of relief, or clarify the relief sought, based on the same facts as originally pleaded." … Put somewhat differently, an amendment will be refused when it seeks to advance, after the expiry of a limitation period, a "fundamentally different claim" based on facts not originally pleaded: North Elgin, at para. 23.
[9] Unlike Robins v PricewaterhouseCoopers 2017 ONSC 1778, on which the defendant relies, the proposed amendment in this instance is not a factually distinct claim from what was originally pleaded. A review of the proposed amendments confirms that it does not add any new paragraphs except under the prayer for relief and the deletion of the rationale for not claiming the human rights damages in the original pleading. As noted in Di Filippo v Bank of Nova Scotia 2024 ONCA 33 at paragraph 40:
If a statement of claim pleads all the necessary facts to ground a claim on one or more legal basis, and the original statement of claim only asserts one of the legal bases - that is, one cause of action based on those facts - the statement of claim can be amended more than two years after the claim was discovered to assert another legal basis for a remedy arising out of the same facts - that is, another cause of action. This is because it is only the discovery of the claim, as defined in the Limitations Act and the case law, that is time barred under s. 4, not the discovery of any particular legal basis for the proceeding.
Analysis of Precedent
The principles guiding pleading amendments following limitation period expiry hinges upon established case law. As above, in Kanhai, the court highlighted pivotal cases. Within the highlighted cases, Klassen v. Beausoleil, 2019 ONCA 407, clarified that amendments are permissible where the original pleadings contain the necessary material fact details. In contrast, the case of Robins v. PriceWaterhouseCoopers LLP, 2017 ONSC 1778, illustrated scenarios where amendments would advance distinct claims, consequently falling outside permissible scope. The case of Di Filippo v. Bank of Nova Scotia, 2024 ONCA 33, further solidified that amendments can occur when pleadings sufficiently outline facts relevant to multiple legal bases.
Conclusion
The ability to amend pleadings after the expiry of a limitation period highlights both flexibility and restrictions that are subject to whether the material facts required to support the proposed amendment were sufficiently pleaded prior to expiry of the limitation period.
