Debt Consolidation Mortgage in Canada: Rolling Debt Into Your Mortgage (2026)

How Does a Debt Consolidation Mortgage Work?

You refinance your mortgage for a larger amount and use the extra money to pay off higher-interest debts, typically credit cards, lines of credit, and car loans. Instead of several payments at high rates, you have one mortgage payment at a mortgage rate.

In Canada, a refinance is limited to 80% of your home's appraised value, and a refinance cannot be insured by CMHC, Sagen, or Canada Guaranty (the one exception is building a secondary suite).

How Much Can You Consolidate?

Take 80% of your home's value and subtract your current mortgage balance.

Example (illustrative): home worth $650,000, mortgage balance $420,000.

• 80% of $650,000 = $520,000
• Available for consolidation: $520,000 - $420,000 = $100,000 (before penalties and fees)

You still have to qualify for the new, larger mortgage under the stress test, at the greater of your contract rate plus 2% or 5.25%. Paying off the debts at the same time is what usually makes this work, because those payments disappear from your TDS ratio.

The Monthly Payment Difference

This is why consolidation is popular. Example (illustrative): $40,000 on credit cards and a $25,000 car loan.

The Catch: The Long-Term Cost

Spreading a $65,000 debt over 25 years at 4.5% costs about $43,000 in interest over the full amortization. Paying the same $65,000 off in 5 years at the same rate would cost about $7,600 in interest, at roughly $1,210 a month.

The smart version of a consolidation keeps most of the monthly savings going toward the debt: use your mortgage's prepayment privileges or increase your payment, so the consolidated debt is gone in a few years instead of 25.

The risk to watch: once the credit cards are at zero, the balances creep back up. If that happens, you end up with a larger mortgage and new card debt.

What About the Prepayment Penalty?

Refinancing before your term ends usually means breaking your mortgage. On a variable rate that is typically three months of interest. On a fixed rate it can be the interest rate differential (IRD), which can be large when rates have fallen since you signed.

Ways to reduce or avoid it:

• Blend-and-increase with your current lender: the new money is priced at today's rate and blended with your existing rate, often with a reduced or no penalty
• Wait until renewal, when you can refinance with no penalty
• Use a HELOC or second mortgage and leave the first mortgage untouched

Which Option Fits Your Situation?

Four ways to consolidate using your home:

When Consolidation Is Not the Answer

• The debt is small enough to pay off within a year or two from cash flow
• You are close to 80% loan-to-value already, so there is nothing to consolidate into
• The spending that created the debt has not changed
• The debt is already at a low rate, such as a 0% promotional car loan

In those cases a budget, a balance transfer, or a credit counselling agency may cost less than restructuring a mortgage.
