Negotiations and payment reminders do not, by themselves, extend a statutory lien deadline.
Construction Prompt Payment Act
The official consolidation checked on 4 October 2026, current to 22 September 2026, marks sections 1–51 as not in force. Commencement and transition details need to be checked before using the new framework.
Prompt payment does not issue B.C. prompt-payment dates. Existing contract obligations and Builders Lien Act deadlines can still matter now.

Separate rights can run at the same time
A construction lien is a distinct statutory remedy connected to qualifying work or materials. A payment claim, a prompt-payment notice and an adjudication are not interchangeable with a lien preservation step.
The governing law determines the land or funds affected, who can claim, the triggering event, the period for preservation and any later step required to continue the claim.
The triggering event is fact-sensitive
Completion, abandonment, termination, last supply, certification or other events can matter under different regimes. A date copied from an invoice is not automatically the correct trigger.
Special types of work and projects can change the rule. A generic Canada-wide day count is not a reliable basis for preserving a claim.
Escalate uncertainty early
Keep supply records, contract documents, completion evidence and payment history together. If a lien right may matter, ask a construction lawyer to identify the applicable preservation and follow-on steps while they remain available.
This site deliberately does not calculate lien expiry from a single last-work date. The necessary factual and legal assessment is more involved.
