Which lien regime applies?
The Construction Act's 60-day preservation / 90-day perfection timeline generally applies to contracts entered on or after July 1, 2018; the former Construction Lien Act's 45 / 45 days applies to older contracts. The clock runs from the last day of supply, publication of the certificate of substantial performance, or termination — confirm the correct trigger.

Preserve by registering a claim for lien; perfect by commencing an action and registering a certificate of action. Timelines are strict — Construction Act, R.S.O. 1990, c. C.30, ss. 22, 31, 36. The January 1, 2026 amendments did not change these timelines.
Estimate only — not legal advice. Confirm the trigger event, the applicable regime, and holdback obligations with the solicitor of record.
