Limitation deadline calculator
Missing the limitation deadline is the single most avoidable way to lose. Enter when your dispute arose and see your likely filing cutoff.
The clock usually starts the day you discovered the loss, not the day the contract was signed. This tool applies the standard period for your region; unusual claim types can differ, so treat the result as a strong guide rather than a guarantee.
Calculate my deadline
Why the start date matters
The "discoverability" rule means the period often begins later than people expect. If a contractor's faulty waterproofing only caused a visible leak 14 months after the job, the clock may start at the leak, not the original work. Document when you first noticed the problem, because that date can extend your window.
Events that can reset the clock
In many jurisdictions a written acknowledgment of the debt, or a partial payment, restarts the limitation period from zero. If a debtor sent you an email last month admitting they owe you, that can revive a claim you thought was stale. Keep every such message.
Frequently asked questions
What is a limitation period?
A limitation period is the legal time limit for starting a lawsuit. Once it expires, the court will dismiss your claim even if it is otherwise valid. The clock usually starts when you knew, or should have known, about the loss.
How long do I have to file a small claims case in Ontario?
Ontario's basic limitation period is two years from the date you discovered the claim, under the Limitations Act, 2002. A few claim types have different periods, so confirm yours.
Do limitation periods differ in the US?
Yes, significantly. They are set by each state and by claim type. Written contracts often allow four to six years, oral contracts two to four, and personal injury one to three. Always verify your state's statute of limitations.
Can a limitation deadline be paused?
Sometimes. The clock can be paused ('tolled') for minors, for people who are incapacitated, or where the defendant concealed the problem. Partial payment or written acknowledgment of a debt can also restart it.
What should I do if my deadline is close?
File immediately. You can refine details later, but starting the claim stops the limitation clock. If only days remain, prioritise filing over polishing your paperwork.
