What is the time limit to sue for a latent defect?
Short answer
In Quebec, the limitation period for a latent defect (vice caché) is 3 years, and it runs from the discovery of the defect — or, where the defect appears gradually, from the moment its seriousness can be suspected.
In detail
The starting point is therefore not the date of purchase, but the date of discovery. That is what the Gouvernement du Québec specifies on its page about time limits in small claims: the 3-year period runs “from its discovery”, and for a defect that shows itself gradually, from “the moment you suspect how serious the problem is”.
This nuance cuts both ways. It lets you claim for a problem that arose long after the purchase, but it requires you to pinpoint the moment of discovery — because that moment fixes the end of the period, and because the other party may argue that you knew earlier.
A latent defect is also a claim where technical evidence carries a lot of weight: the government lists the expert’s report and the damaged item among the evidence that can be filed in small claims.
What to document
The date and the circumstances of the discovery: the first symptom, the first thing you noticed was wrong, the first call to the seller or to a professional. Keep time-stamped photos, inspection reports, repair invoices, and the item itself if that is possible.
Put your facts in writing, free. Writing your version down early, keeping your documents dated and preparing your questions for a lawyer: the tool is there to document, never to advise.

What this page is not
This is general legal information about the law of Quebec and Canada, dated and sourced. It is not legal advice, not a strategy, and not a prediction about the outcome of a case. In Quebec, only lawyers and notaries may give legal advice (Act respecting the Barreau du Québec, ss. 128 and 133). Laws and amounts change: the official source always prevails over us.
