Finding out a stranger or government agency can attach a legal claim to your home is unsettling. In Ontario, a property lien is a tool creditors and authorities use to make sure a debt eventually gets paid — and yes, in many cases they can register one against your house without a long court fight. If you are worried about a lien, behind on bills, or trying to plan ahead, knowing exactly who can put a lien on your house in Ontario is the first step to protecting your equity.
This 2026 guide walks through every party in Ontario that has the legal right to register a lien against residential property, what each type of lien actually does, and the practical steps to remove or challenge one. We will also cover what a lien means for selling, refinancing, or living in your home — because the answer is more nuanced than most homeowners realize.
What Is a Property Lien in Ontario?
A lien is a legal claim registered against real estate to secure a debt or obligation. Once it is registered on title at the Ontario Land Registry, the property cannot usually be sold or refinanced without that debt being addressed. Some liens are voluntary — a mortgage is the most common example, where you agree to give the lender a claim against the home as part of the loan. Others are involuntary and arrive without your consent because a statute or court order allows them.
Involuntary liens in Ontario typically come from one of five sources: unpaid government debts (federal, provincial, or municipal), unpaid construction work under the Ontario Construction Act, secured lender defaults, civil court judgments, and condominium common-element arrears. Each operates under its own rules — and each has its own removal process. Understanding which type you are dealing with changes everything about how you respond.
The most common parties in Ontario with the legal authority to register a lien against your home include the Canada Revenue Agency for federal tax debts, your municipality for unpaid property taxes, contractors and tradespeople under the Construction Act, mortgage lenders and home equity creditors, judgment creditors who have won a civil court action, and condominium corporations when common element fees go unpaid. If you owe money you cannot fix on your own, a structured solution like tax debt relief or credit debt relief may stop things from escalating to a lien in the first place.
Pros of Acting Quickly on a Lien
Stops Interest from Growing
CRA and judgment debts keep accruing interest until paid. Acting fast caps the damage.
Protects Your Equity
Resolving a lien before a forced sale means you keep more of the value built up in your home.
Restores Refinance Options
Lenders will not refinance against a clouded title. A discharged lien reopens the door to debt consolidation.
Removes the Title Cloud
Buyers, lawyers, and lenders see liens during searches. Clearing them up keeps future deals simple.
Risks of Ignoring a Lien
Forced Sale Risk
The CRA and judgment creditors can seek a writ of seizure and force a sale of the property.
Cannot Sell or Refinance
Title insurers and real estate lawyers will block any transaction until the lien is paid out.
Compounding Costs
Legal fees, accrued interest, and enforcement costs are added to the original balance.
Credit Score Damage
Liens reported through judgments and bankruptcy filings can sit on your credit report for years.
Who Should Take Immediate Action
- Homeowners who have received a Notice of Continuation or formal lien registration letter
- Anyone trying to sell or refinance their Ontario home in the next 12 months
- Property owners who received a Claim for Lien from a contractor or subcontractor
- Taxpayers who have ignored CRA collection letters for more than 90 days
- Homeowners facing a writ of seizure and sale filed at the local sheriff’s office
- Anyone whose property taxes have been unpaid for two or more years
Who Can Probably Slow Down and Get Advice First
- Homeowners who suspect the lien was registered in error or on the wrong property
- People served with a contractor lien outside the 60-day registration window under the Construction Act
- Owners whose property has so much equity that any forced sale would clearly pay the debt
- Anyone disputing the underlying debt — paying first can waive your right to challenge
- Homeowners weighing a consumer proposal or other formal debt solution that would address the lien holistically
A Real-World Example: How a CRA Lien Plays Out
Consider Priya, a self-employed graphic designer in Mississauga who fell three years behind on income taxes during a slow stretch. By 2026 she owes the Canada Revenue Agency about $24,000 in tax, interest, and penalties combined. She owns a townhouse worth $620,000 with a $310,000 mortgage. Here is what registering a CRA lien actually looks like in her case:
The lien itself does not change Priya’s day-to-day life. She keeps living in her home, the locks stay the same, and there is no marshal at the door. But the moment she tries to refinance her mortgage at renewal, sell, or take out a home equity line of credit, the CRA lien must be paid in full. Interest also continues to accrue on the underlying tax debt, so waiting only makes the balance grow. If a job loss or other emergency added unsecured debt on top — see debt management after job loss — a structured plan may be a better answer than chipping away alone.
Step-by-Step: How to Deal With a Lien on Your Ontario Home
- Get a copy of the lien registration. Order a parcel register search from the Ontario Land Registry through an online service provider or your real estate lawyer. The document tells you exactly who registered the lien, the amount claimed, and the date.
- Identify the lien type. CRA tax lien, municipal tax arrears, construction lien, mortgage charge, judgment, or condo lien — each has different rules and different urgency. The registration document and creditor name make this clear.
- Verify the debt and the amount. Contact the creditor directly and request a written statement of account. Errors are common — wrong amounts, paid balances, and even wrong property addresses do happen.
- Check the registration timeline. Construction liens, for example, must be preserved within 60 days of the last work or supply under the Ontario Construction Act. Liens registered late can be challenged in court.
- Decide whether to dispute or pay. If the debt is valid and the amount is right, paying is usually fastest. If you have a real dispute, file a court application — but be aware of the cost.
- Negotiate a payment plan if needed. The CRA, municipalities, and most contractors will accept structured payment arrangements. Get any arrangement in writing and tied to a lien discharge upon completion. The CRA’s own collections page outlines what they expect.
- Obtain and register the discharge. Once the debt is paid or settled, the creditor must provide a discharge document. Your lawyer registers it at the Land Registry to clear the title.
- Consider broader debt solutions. If multiple liens are stacking up or the underlying debt is unmanageable, a consumer proposal or other formal arrangement may resolve everything at once. Talk to a Licensed Insolvency Trustee or a debt advisor before things escalate.

Frequently Asked Questions
Can the CRA put a lien on my house in Ontario without going to court?
The CRA cannot register a lien on your home purely on its own assessment. It first has to certify your debt in Federal Court or obtain a provincial judgment. Once that certification or memorial is in place, however, the CRA can register a charge against your property in Ontario without any further court appearance from you. According to the CRA’s own collections guidance, you should usually receive a letter informing you that the debt has been certified before any action is taken against your property.
How long does a contractor have to file a lien on my property in Ontario?
Under the current Ontario Construction Act, a contractor, subcontractor, or material supplier generally has 60 days after the last day of supplying services or materials to preserve a lien by registering a Claim for Lien on title. After that, they have another 90 days to perfect the lien by starting a court action. If those deadlines are missed, the lien rights expire. This is a major change from the older Construction Lien Act, which gave 45 days — so always confirm which timeline applies to your project based on when the work began.
Will a lien on my Ontario house affect my credit score?
The lien registration itself is not automatically reported to Equifax or TransUnion. However, the underlying debt that caused the lien — a judgment, missed mortgage payments, or unpaid taxes that turned into a court order — usually is reported. Judgments in particular stay on your credit report for six years from the date filed. So while the lien on title is a separate legal issue, it almost always travels with credit damage from the original unpaid debt.
Can I sell my home if there is a lien on it?
Technically yes, but practically the lien must be paid out at closing. Real estate lawyers conduct a title search before any sale closes, and they will require any registered liens to be discharged from the sale proceeds before transferring title to the buyer. If the sale price is not high enough to cover the mor
