- Key issue
- Whether a plaintiff can amend their statement of claim to introduce new facts and a new cause of action after the two-year limitation period has expired under Ontario's Rules of Civil Procedure.
- Outcome
- The court dismissed the motion to amend the pleadings and refused to issue summonses to witnesses, finding the proposed amendments were time-barred and the record was insufficient to justify the relief sought.
- Why it matters
- If you wait too long to update your lawsuit with new facts or claims, an Ontario court may permanently bar those amendments — even if you believe you have a strong case on the merits.
Legal principle
The rule from this case
Under Rule 26.01 of Ontario's Rules of Civil Procedure, courts generally allow amendments to pleadings at any stage of a proceeding — but that general openness has a critical limit. When the limitation period for the new claim has already expired, the court treats the expiry itself as a form of non-compensable prejudice to the opposing party. Money cannot fix that kind of prejudice because the defendant has lost the legal right to be free from a time-barred claim. For an amendment to succeed after the limitation period has run, the plaintiff must show that the proposed changes do not introduce a genuinely new cause of action — or that discoverability principles push the clock forward to a point within the limitation window. Simply wanting to tell a different or expanded version of events is not enough. If the proposed amendment rests on facts that are substantially different from the original claim and those facts were discoverable years earlier, Ontario courts will refuse the amendment.
Important limits
What this does not mean
This decision does not mean that amendments to pleadings are routinely refused in Ontario. Courts grant amendments frequently, especially early in a proceeding when the limitation period has not expired and the other side can be compensated with costs for any inconvenience. Rule 26.01 still creates a strong presumption in favour of allowing amendments in ordinary circumstances. The ruling also does not stand for the proposition that a plaintiff is forever stuck with a poorly drafted original claim. If new facts emerge within the limitation period, or if the amendment merely clarifies or particularizes an existing claim rather than introducing a brand-new cause of action, the analysis is entirely different. The key lesson is timing and the nature of the change — not a blanket prohibition on updating your pleadings.
Can you change what your lawsuit is about after filing it in Ontario?
Yes — but only within limits. Ontario’s Rules of Civil Procedure allow parties to amend their pleadings at almost any stage, but courts will refuse an amendment when it introduces a fundamentally different claim and the limitation period for that new claim has already expired. In Rajbally v. TD Canada Trust, 2026 ONSC 4270 (CanLII), the Ontario Superior Court of Justice dismissed a motion to amend a statement of claim on exactly those grounds.
What is Rule 26.01 and when does it apply?
Rule 26.01 is the provision in Ontario’s Rules of Civil Procedure that governs amendments to pleadings. Under that rule, a court shall grant leave to amend on such terms as are just — unless the amendment would cause prejudice that cannot be compensated by a costs award. The rule is deliberately generous: the default is to allow amendments so that disputes can be resolved on their true merits. The critical exception is non-compensable prejudice, which arises most commonly when the limitation period for the proposed new claim has already expired.
What counts as non-compensable prejudice in Ontario litigation?
Non-compensable prejudice means harm to the opposing party that money (a costs award) cannot adequately fix. The clearest example is a limitation period defence. Once the two-year limitation period under Ontario’s Limitations Act, 2002 has run, the defendant has a legal right to be free from that claim. If a court were to allow an amendment introducing a time-barred cause of action, it would strip the defendant of that vested right — and no amount of costs could restore it. In this case, the proposed amendments alleged false credit reporting and a card suspension spanning roughly 2012 to 2016, replacing the original claim’s factual foundation. The court found those events were discoverable well before the motion was brought, and discoverability had not even been pleaded to explain the delay.
How did the court apply the limitation period analysis here?
The court applied a well-established line of Ontario authority — including 100997 Ontario Limited v. North Elgin Centre Inc. and McFadden v. Psutka — holding that expiry of the limitation period constitutes non-compensable prejudice that defeats a motion to amend. The proposed pleading was not merely a refinement of the original claim. It alleged entirely different facts: a different TD product, different conduct, and a different time frame. Because the plaintiff had not pleaded any basis for discoverability that would bring the claim within the limitation window, the presumption of prejudice to the defendant was not rebutted. Leave to amend was refused.
What happened with the request to issue summonses to witnesses?
The plaintiff also sought to have the court issue summonses requiring witnesses to attend at trial. Ontario’s simplified procedure (Rule 76) contemplates that trials in that stream proceed as summary trials under Rule 76.12. The court found two problems: no trial had been scheduled, and the record before the court was inadequate to justify issuing summonses. Without a scheduled trial date and a sufficient evidentiary basis, the court was not satisfied that the relief was appropriate. The motion for summonses was dismissed as well.
Practical takeaways for plaintiffs in Ontario civil litigation
- Act quickly when facts change. If you discover new information that might affect your claim, bring a motion to amend as soon as possible — ideally before the two-year limitation period for any new cause of action expires.
- Check whether your amendment introduces a new cause of action. Courts distinguish between clarifying an existing claim (usually allowed) and introducing a fundamentally different claim (often refused if time-barred). Get legal advice before drafting amended pleadings.
- Plead discoverability if you rely on it. If you argue that the limitation clock started later than the event itself, you must actually plead the facts that support discoverability. Leaving that out can be fatal to a motion to amend.
- Do not assume courts will overlook long delays. A significant gap between the underlying events and the motion to amend is a red flag. Courts will scrutinize whether the defendant’s limitation defence has been prejudiced.
- Ensure procedural steps are in order before bringing motions. The summons issue in this case is a reminder that courts require a proper record and the right procedural context — such as a scheduled trial date — before granting relief.

FAQ
Frequently asked questions
If the two-year limitation period has expired for a particular claim, a court will likely refuse to allow you to add or amend that claim in your lawsuit. The defendant gains a vested right to be free from time-barred claims, and courts treat that as prejudice that cannot be fixed by a costs award.
You may be able to amend if the amendment does not introduce a new cause of action and simply clarifies or particularizes your existing claim. However, if the amendment raises entirely different facts or a new legal claim, and the limitation period has expired, the court will very likely refuse it.
Ontario's simplified procedure (Rule 76) is a streamlined litigation process for claims up to $200,000. Trials in that stream proceed as summary trials under Rule 76.12, and procedural steps like issuing witness summonses must be taken in the proper context — including having a scheduled trial date and an adequate record before the court.
