Anonymised, illustrative composite. A small Ontario general contractor had a $58,000 lien registered against a project over a scope dispute it believed was overstated. The lien blocked the owner’s financing draw — and the GC separated that problem from the underlying dispute in ten days.
At a glance
The GC was small enough that a single blocked financing draw could stall payroll and supplier accounts across every other trade on the job, not just the one in the dispute. It had never dealt with a registered lien before and initially treated it the way it would treat any other invoice dispute — something to negotiate through slowly — until its lender made clear the draw would not move with a lien still on title, no matter how the underlying argument was going.
The GC and a subtrade disagreed sharply on how much extra work a change in the project actually justified. The subtrade registered a construction lien for $58,000 against the property, a figure the GC believed was significantly overstated relative to the work actually performed. Whatever the merits, the lien did what a registered lien does — it attached to title, and the owner’s lender would not release its next construction financing draw with an unresolved lien on the property.
With the draw on hold and trades on other scopes waiting to be paid from it, the GC faced two very different clocks running at once: how long the $58,000 scope dispute would take to actually resolve, and how long the project could go without its next financing draw. The two did not need to move at the same speed, but only if the GC could separate them.
Ontario’s construction lien scheme gives exactly that separation: a lien can be vacated from title by paying security into court — the amount claimed plus an allowance for costs, subject to a cap. Doing so does not resolve who is owed what; it only removes the lien’s hold on the property itself, which is precisely the piece blocking the financing draw.
There was also a real incentive for the subtrade to have priced its claim honestly: a wilfully exaggerated lien, or one registered knowing there is no basis for it, exposes the claimant to liability for the damages that registering it caused. That is not a fact the GC needed to prove here, but it shaped how it framed the dispute with the subtrade once title was clear and the pressure of a blocked draw was gone.
$58,000 claimed on the registered lien. Security posted into court at the claimed amount plus the allowed costs component. Under s.44(1) of the Construction Act, that costs component is the lesser of $250,000 or 25 per cent of the amount claimed — on a $58,000 lien, a further $14,500, for total security of $72,500. Ten business days between the court application to vacate and the lien coming off title, after which the financing draw proceeded on its normal schedule — a delay measured in days rather than however long the underlying scope dispute might otherwise have taken to resolve on its own. The GC treated the posted security as effectively frozen working capital until the scope dispute settled, which was the real cost of moving fast, and budgeted for it as such rather than being surprised by it later.
The bind is what doing nothing would have cost against what posting security actually cost. Left alone, the lien would have stayed registered against title for its full statutory life, financing would have stayed blocked, and the underlying $58,000 dispute could easily have run for months before resolving on its own timeline — with the whole project’s cash flow held hostage to a dispute over one subtrade’s invoice the entire time. Paying security into court let the GC keep the project moving immediately while the actual money dispute continued on its own, separate track.
The financing draw proceeded on schedule once title cleared, and the $58,000 scope dispute continued to be negotiated between the GC and the subtrade without holding the rest of the project hostage to it.
