CRA Super Priority Liens and the Sale of the Matrimonial Home in Ontario

9 Jul 2026 5 min read No comments Family Law & Divorce Ontario
💡

If your spouse’s business owes unpaid HST or employee payroll deductions, the Canada Revenue Agency (CRA) holds a legally enforceable “super priority” lien. However, this lien can only be enforced against your debtor spouse’s share of the proceeds. Under Ontario law, your 50% interest in the matrimonial home remains fully protected from their individual tax debt.

Dividing property during a separation is complex enough, but the situation becomes critically dangerous when the Canada Revenue Agency (CRA) gets involved. In Ontario, spouses generally expect to equally share the value of the matrimonial home under the Family Law Act. However, if one spouse operates a business and has failed to remit certain taxes, the federal government can attempt to disrupt your property division. Fortunately, Ontario law heavily protects the non-debtor spouse’s interest in these situations.

Specifically, the CRA relies on a legal concept known as a “deemed trust.” When a business collects Harmonized Sales Tax (HST) from customers or deducts income tax, CPP, and EI from employees’ paycheques, those funds never belong to the business owner. 💵 They are considered to be held in trust for the Crown. If those funds are not remitted, the CRA enforces a super priority lien on the business owner’s assets, which targets their interest in jointly owned real estate, including your shared matrimonial home.

Step-by-Step Process: When the CRA Intervenes in an Ontario Divorce

Whether you are navigating a divorce in Toronto, Hamilton, or Ottawa, the CRA’s reach spans across the entire country. However, because property rights are governed by provincial law, the CRA’s collection remedies are restricted to the debtor spouse’s actual share. If you suspect your spouse has tax arrears, you must approach the sale of your home with extreme caution. Here is how a CRA intervention typically unfolds during the property division phase.

Step 1: The CRA Audit and Deemed Trust Assessment

The process usually starts when the CRA audits your spouse’s business and discovers unremitted source deductions or HST. The CRA will issue a formal assessment demanding payment. 📋 Because these funds are part of a deemed trust, the CRA does not need to go to court to win a judgment against your spouse. The debt is automatically attached to your spouse’s assets from the moment the taxes were supposed to be remitted.

Step 2: The CRA Registers a Lien on the Matrimonial Home

If the tax debt remains unpaid, the CRA will register a lien against the title of your matrimonial home at the local Land Registry Office. Even if only one spouse is on the title, or if both spouses own it as joint tenants, the lien attaches to the property. This registration serves as a public declaration that the property cannot be sold or refinanced without first satisfying the federal government’s tax claim.

Step 3: Selling the Home and the Interception of Funds

When you and your ex-partner eventually sell the home as part of your divorce settlement, your real estate lawyer must conduct a title search. Upon finding the CRA lien, the lawyer is legally obligated to contact the CRA for a payout statement. 🏡 Following the landmark Ontario Court of Appeal decision in Senthillmohan v. Senthillmohan, any individual tax debt owed to the CRA is deducted solely from the debtor spouse’s 50% share of the net proceeds. The non-debtor spouse’s share cannot be touched to satisfy these arrears, and their portion must be released to them.

Step 4: Adjusting the Equalization Payment in Family Court

Once the CRA has deducted the debt from your spouse’s share, the remaining equity belonging to your spouse is significantly reduced. In the Superior Court of Justice, you and your family lawyer will use the Net Family Property (NFP) calculations to finalize the division of assets. Because your personal 50% share of the home’s proceeds is protected from the tax lien, your financial position is safeguarded, though any further equalization payments owed to you by your spouse may be harder to collect if their remaining funds are depleted.

How Much Can a CRA Lien Cost You?

Dealing with a CRA super priority claim can devastate the financial outcome of your separation. You must factor in several severe financial implications:

  • The Tax Debt Itself: CRA liens can range from a few thousand to hundreds of thousands of dollars, completely wiping out the equity in a home.
  • Accrued Interest and Penalties: The CRA charges compounding daily interest on unpaid tax balances, heavily inflating the original amount owed.
  • Legal Fees: Family lawyers and tax lawyers in Ontario typically charge between $350 and $700 CAD per hour. You will likely need both to untangle the mess and renegotiate your separation agreement.
  • Title Search and Real Estate Fees: Clearing complex liens adds extra administrative costs to your real estate transaction upon closing.

How Long Does the Process Take?

In Canada, dealing with the CRA can drastically slow down your divorce proceedings. While a standard home sale might close in 30 to 60 days, negotiating a payout statement or disputing a lien amount with the CRA can delay your closing for several months. Furthermore, finalizing your equalization in family court can take 1 to 2 years if the loss of equity forces you into a bitter litigation battle over who should bear the burden of the tax debt.

Frequently Asked Questions (FAQ)

Can I protect my half of the house from my spouse’s CRA debt?

Yes, absolutely. Under Ontario law, specifically the landmark Court of Appeal ruling in Senthillmohan v. Senthillmohan, a creditor-including the CRA-cannot seize or collect debt from the share of a non-debtor joint owner. Any individual tax debt, including deemed trust claims, must be paid strictly out of your spouse’s 50% share of the net sale proceeds, leaving your 50% interest fully protected.

Does a regular CRA income tax debt have super priority?

No. Super priority generally applies strictly to “deemed trust” amounts-specifically unremitted HST/GST and employee payroll deductions (source deductions). Regular personal income tax debt is treated as a standard unsecured debt until the CRA explicitly registers a certificate on title.

What happens if there isn’t enough equity to pay the CRA?

If the house is sold and your spouse’s 50% share of the proceeds is not enough to cover their CRA debt, the CRA will take whatever is available from your spouse’s portion. The unpaid balance remains your spouse’s personal liability. Your 50% share of the net proceeds remains untouched and is released to you, provided there is enough total equity to satisfy the joint primary mortgage first.

Should I finalize my separation agreement before the house is sold?

You must have a lawyer conduct a title search first. If you finalize a separation agreement assuming you will receive a specific amount of money from the house sale, a surprise CRA lien at closing will completely invalidate your financial calculations.
