These are official government and court sources for general contractor bankruptcy recovery, grouped by province and territory. ArtBuild checked each link on the date shown. Always read the current official version for your project; laws and forms change.

Your province or territory decides most of the rules: liens, holdback, prompt payment, consumer protection and the courts. Federal law adds bankruptcy and insolvency, and prompt payment on federal property.

Key time limits: construction liens

A lien (in Quebec, a legal hypothec) is a claim against the property you improved. It is lost if it is not registered in time, and a registered lien is lost if the next step is not taken in time. The periods below are quoted from each statute as checked on 2026-10-24. The event that starts the clock depends on your contract and role, and some Acts count "clear" days, so read the section for your situation and act well before the last day.
