When does your builders' lien have to be registered?
For trades and small firms working in Canada. Builders'-lien deadlines vary by province and are strict - miss them and you lose your lien rights.
What this tool does
Applies your province's builders'-lien deadline (or Quebec's legal-hypothec window) to your last-work or substantial-completion date and shows the date by which you must register.
What the law actually says
- •Builders'-lien deadlines are strict and vary by province - from 30 days (NL, Yukon) to 60 (most), with Saskatchewan at 40 clear days and BC/Nunavut at 45. Miss it and you lose your lien rights. Quebec uses a legal hypothec (30 days to register, 6 months to act). Holdback is separate - see the Holdback Calculator. Confirm the exact deadline in your province's lien legislation.
