Construction Lien Perfection (Court Action + Certificate)

Lien perfection is the second statutory step in the lien process, distinct from lien preservation. Preservation is registering the lien itself against title at the land registry; perfection is commencing a court action to enforce the lien and registering a Certificate of Action (in Ontario) or equivalent. In Ontario, the perfection window is 90 days after the lien preservation date (Construction Act s.36). British Columbia requires a court action within 1 year of filing the lien (Builders Lien Act s.33). Alberta requires statement of claim plus lis pendens within 180 days of registration. New Brunswick allows 1 year. Saskatchewan and Manitoba allow 2 years. Nova Scotia requires court action plus lis pendens within 105 days total from last supply. Quebec uses a 6-month action window after the legal hypothec is preserved. Miss the perfection step and the preserved lien is extinguished; the preservation alone is not enough.

Why it matters to Canadian contractors

A preserved-but-unperfected lien is worthless. Many contractors register a lien and then sit on it, believing they have years to enforce. Most provinces give 90 days to 1 year and the clock runs from preservation, not from when payment becomes due.
Perfection turns the lien into a defended legal claim. Without perfection, the owner can apply to vacate the lien on a routine motion.
The court action commenced for perfection is the same lawsuit that will eventually try the underlying payment dispute. Drafting it correctly matters because it frames the entire dispute.
Owners and GCs routinely settle preserved liens before the perfection deadline to avoid the cost and risk of a court file. The perfection clock is your leverage to negotiate.

Common mistakes and pitfalls

The perfection deadline is from the date of lien registration, not from the date of last supply. Mixing these up burns 30 to 45 days of your window.
Filing a generic Statement of Claim is not enough. The claim must specifically reference the lien, the property, and the unpaid amount. Sloppy pleadings can be struck.
In Ontario, the Certificate of Action must be registered on title in addition to filing the court action. Doing only one is treated as not perfecting at all.
Once perfected, the lien stays alive until the court rules. But you cannot let the action languish; courts can dismiss for delay and the lien dies with the action.
Vacating a perfected lien requires posting security with the court (usually the full lien amount plus 25 percent for costs). This is the financial cliff that pushes most owners to settle.
