Owe the CRA? How Ontario homeowners use a refinance to clear tax or HST arrears, what lenders require first, a worked example, and when not to.
Quick answer: Many lenders will refinance a home to pay off money owed to the CRA, as long as every tax return is filed and the arrears are paid directly from the mortgage funds at closing. It stops daily-compounding interest and CRA collection action, but the cause — usually missed instalments — has to be fixed too.
Tax debt builds quietly, especially for self-employed people, commissioned salespeople and anyone with rental or side income. A big balance due in April becomes a payment arrangement, then interest on top of interest.
CRA debt is also the one creditor with collection powers no bank has. This guide explains why that changes the urgency, what a lender needs before it will pay the CRA off, and a worked example.
Most repeat tax debt comes from not paying instalments on income that has no tax taken off. Before or alongside the refinance, set up quarterly instalments, move tax money to a separate savings account each time you're paid, and have an accountant check your instalment amounts.
If penalties or interest built up because of hardship, illness or a CRA delay, you can ask for them to be cancelled through the CRA's Taxpayer Relief program for up to ten calendar years back. It's discretionary, but worth asking before you borrow to pay it.

A self-employed contractor in Orillia owes $38,000 in income tax, penalties and interest and has a CRA payment arrangement of $1,500 a month. The mortgage is $410,000 at 4.5% (variable) with 18 years left, so breaking it early costs three months' interest.
| Today | Balance | Rate | Monthly |
|---|---|---|---|
| Mortgage (18 years left) | $410,000 | 4.5% | $2,764 |
| CRA balance (tax, penalties and interest) | $38,000 | prescribed rate, compounds daily | $1,500 |
| Total monthly today | $4,264 |
Costs added to the new mortgage: Prepayment penalty (three months' interest) $4,613; Legal and appraisal (estimate) $1,500. New mortgage: $454,113 at 4.5% (illustrative rate, not a quote).
Rates in this example are illustrations, not quotes. Payments use Canadian mortgage maths (interest compounded semi-annually).
Lenders generally let your total mortgage reach 80% of your home's value when you refinance. Using the MLS® Home Price Index benchmark for a typical home from the Toronto Regional Real Estate Board's August 2026 report:

|---|---|---|
| Simcoe County (all areas) | $775,100 | $620,080 |
| Barrie | $624,700 | $499,760 |
| Orillia | $504,600 | $403,680 |

Usually, yes. Most lenders will refinance to pay off CRA debt as long as every return is filed, your income supports the new mortgage, and the CRA is paid directly from the mortgage funds at closing.
Yes. For unpaid tax the CRA can register a lien against your property after giving notice. It has to be paid and discharged before you can sell or refinance, which is usually done on closing day.
It's possible, but timing matters. An institutional lender may take a few weeks; if garnishment is hurting your cash flow, a short-term alternative or private mortgage can stop it faster, followed by a refinance with a bank lender.
If the balance is small and you can clear it within a year or so, an arrangement may cost less than legal, appraisal and penalty costs. Interest keeps compounding daily during an arrangement, so larger balances usually cost less in a mortgage.
Sometimes. The Taxpayer Relief program lets you ask the CRA to cancel penalties and interest caused by circumstances beyond your control, such as illness or hardship, for up to ten calendar years back. It isn't automatic.
