Construction Lien Registration
When payment is delayed, timing and precision matter. We assist contractors, subcontractors, and suppliers with Ontario construction lien registration, handled with the care these matters require.
A construction lien is often the first meaningful step in protecting payment rights on an Ontario project. When an account remains unpaid, the question is not simply whether a claim exists, but whether it is preserved properly and on time.
Our role is to register the lien efficiently and accurately, so you can focus on the dispute itself rather than the mechanics of filing.

Why register a lien
Ontario construction lien rights are time-sensitive. Once the applicable deadline passes, the ability to preserve the claim may be lost.
A properly registered lien can create immediate leverage and encourage prompt attention to the unpaid account. It is a formal step, and one that should be approached with care.

Deadlines should be treated seriously
Construction lien deadlines in Ontario are strict. The preservation period is short, and further steps may be required within a separate perfection timeline.
If you are unsure how much time remains, it is best to have the matter reviewed without delay. In lien matters, waiting often reduces options.
