Yes — and it's one of the more disruptive tools in the CRA's collection toolkit, because a lien attaches to your property itself, not just your income or bank accounts. Once registered, it surfaces on a title search, complicates a sale or refinance, and generally has to be dealt with before clear title can pass.

A CRA lien isn't automatic the moment you owe tax. It typically follows collection escalation — an unpaid, finalized debt certified as a court judgment — after which the CRA can register against real property much like any other judgment creditor.

This article explains how a CRA lien gets registered, what it means for selling or refinancing, and what to do about it.

How a CRA Lien Gets Registered

Once an unpaid tax debt has been certified and registered as a Federal Court judgment, the CRA can register that judgment against real property you own in Ontario, the same way any judgment creditor can register against a debtor's land. The lien attaches to your ownership interest in the property and stays registered until it's paid, negotiated, or otherwise resolved.

This is a civil, administrative-style process rather than a court hearing about the property itself — the lien formalizes an existing debt against a specific asset, it doesn't create a new one.

Effect on Selling or Refinancing

A registered lien shows up on a standard title search, which almost every buyer's lawyer and every mortgage lender will run. In practice:

Sole Ownership vs. Joint Ownership

ScenarioGeneral effect
You own the property aloneThe lien attaches to the full property, since it's all your interest.
Jointly owned with someone who has no CRA debtThe lien generally attaches to your interest in the property, not your co-owner's — but in practice it still complicates any sale or refinance of the whole property, since both owners' cooperation and clean title are needed.
Jointly owned and both owners have the debtBoth interests can be affected.

Joint ownership doesn't reliably protect an innocent co-owner from the practical disruption of a lien, even where it doesn't legally attach to their share — this is a common and frustrating misunderstanding.

Don't Confuse a CRA Lien With Other Property-Related Taxes

Land Transfer Tax, municipal property tax, and a CRA tax lien are three separate things:

Treating these as interchangeable is a common and costly mistake when trying to figure out what's actually owed and to whom.

Frequently asked questions

Does a CRA lien mean I have to sell my house?

No. A lien doesn't force a sale by itself. It becomes a practical problem mainly when you try to sell, refinance, or otherwise deal with the property.

Can the CRA register a lien without telling me first?

The CRA typically sends collection notices well before reaching this stage, but the lien registration itself is a filing process, not a hearing. You may not get a separate notice at the moment of registration, so don't wait for one if you know a debt has escalated this far.

How is a CRA lien different from land transfer tax or property tax arrears?

These are three separate things, as explained above. None of the three should be confused with the others when you're trying to understand what you owe and to whom.

Can I sell the property to a family member to avoid the lien?

A lien follows the property and the debtor's interest in it, and a transfer made to get around an existing or anticipated debt can raise its own serious legal problems. Get legal advice before attempting any transfer once a debt or lien is in the picture.
