To file a construction lien in Ottawa, you must strictly follow the Ontario Construction Act, which requires you to register the lien within exactly 60 days of your last day of supplying services or materials. Hiring a local real estate or civil litigation lawyer to draft and register the lien typically costs between $500 and $1,500 CAD.
Working in the construction industry means you rely on a steady flow of payments to keep your business running, pay your crew, and buy materials. When a property owner or a general contractor in Ottawa refuses to pay for the work you completed, it can be financially devastating. 🚨 Fortunately, the law in Ontario provides a highly effective tool to help you get paid: the construction lien. By placing a lien on the property you worked on, you essentially freeze the owner’s ability to sell or refinance the house until your debt is settled. However, the rules surrounding liens are incredibly strict, and missing a deadline by even one day will permanently destroy your right to claim the money. In this guide, we will break down the exact steps and requirements needed to protect your hard-earned money in the Ottawa construction market.
Step-by-Step Process in Ottawa
Filing a construction lien is a fast-paced legal procedure. Whether you were building a custom home in Kanata, renovating a condo in the ByWard Market, or supplying lumber to a commercial site in Nepean, the process generally follows these steps.
Step 1: Calculating the 60-Day Deadline
The very first and most critical requirement is confirming your timeline. Under the Ontario Construction Act, you have exactly 60 days from the date you last supplied services or materials (or the date the contract was abandoned/terminated) to officially register the lien. 📅 Returning to the site to fix a minor deficiency does not normally extend this strict 60-day clock.
Step 2: Conducting a Title Search
You cannot lien a property if you do not know exactly who legally owns it. Your lawyer will conduct a title search using the provincial Teraview system to find the correct legal description of the Ottawa property and the exact spelling of the registered owner’s name. Any mistake in the owner’s name can invalidate your entire lien.
Step 3: Drafting and Registering the Claim for Lien
Your lawyer will draft a formal “Claim for Lien” document detailing how much you are owed and what work was performed. In Ontario, this document is filed electronically against the property’s title at the local Land Registry Office. Once registered, it becomes a public record that instantly warns any bank or buyer that there is an active dispute over the property.
Step 4: Perfecting the Lien
Registering the lien is only the first half of the battle. To keep the lien alive, you must “perfect” it within exactly 90 days of the last day your lien could have been preserved under Section 36 of the Construction Act. This gives you a total of 150 days (60 days to preserve + 90 days to perfect) from your last day of supplying materials or services. Perfecting simply means you must officially start a lawsuit by filing a Statement of Claim at the Ottawa Courthouse on Elgin Street, and then register a Certificate of Action on the property title.
How Much Does it Cost in Ottawa?
Filing a construction lien requires swift action by a legal professional. Because you cannot easily access the electronic Teraview system yourself, you will need to hire a lawyer or a licensed paralegal. 💲
- Title Search: Accessing the Ontario property records usually costs around $40 to $80 CAD in government disbursements.
- Legal Fees (Registration): Hiring a lawyer to calculate the deadlines, draft the paperwork, and register the initial lien generally involves a flat fee of $500 to $1,500 CAD.
- Government Registration Fee: The province charges a mandatory fee to register the document on title, which under 2026 rates is $85.00 CAD.
- Perfecting the Lien (Lawsuit): If the owner still refuses to pay and you must start a formal lawsuit (perfecting), legal fees will increase significantly, often requiring an initial retainer of $2,000 to $5,000+ CAD to draft the Statement of Claim.

How Long Does the Process Take?
The timeline is completely dictated by the Construction Act. You have a maximum of 60 days to register the lien. Once registered, the property owner will often feel immense pressure from their bank to pay you quickly to clear the title, sometimes resolving the issue in just a few weeks. ⏱ If they refuse, you must launch a lawsuit (perfect the lien) within 90 days of the last day on which your lien could have been preserved (or 150 days from your last day on site), and civil litigation in Ottawa can then take 1 to 2 years to reach a final trial.
Frequently Asked Questions (FAQ)
What happens if I miss the 60-day registration deadline?
If you miss the strict 60-day window, your legal right to register a construction lien is permanently gone. You can no longer encumber the property. However, you can still sue the client for breach of contract in Small Claims Court or Superior Court, but you lose the powerful leverage of the lien.
Can I file a lien for a cash job with no written contract?
Yes, written contracts are not strictly mandatory to file a lien in Ontario, though they make your case much stronger. Verbal agreements are valid, but you must be able to prove the work was requested, completed, and the value of the materials or labour provided (e.g., through text messages or invoices).
Does the property owner have to pay me immediately once the lien is filed?
Not automatically. A lien simply freezes their ability to sell or refinance. If they dispute the quality of your work, they can pay the disputed amount directly into the Ottawa court (paying money into court) to have the lien “vacated” from their title while you both fight over the funds before a judge.
Can I include my lawyer’s fees in the lien amount?
No. Under the Construction Act, the amount claimed in the lien must be strictly limited to the actual value of the services or materials you provided to the property. You cannot inflate the lien amount to cover your legal fees, interest, or punitive damages.
