FAQ Library
Renewal•By Ratellow Research Team•Verified 2026-09-01•How we research

What if my client has a Home Equity Line of Credit (HELOC) combined with their mortgage?

Key Points

  • Lenders will check to make sure you can repay your home equity line of credit (HELOC) along with your mortgage and will monitor your credit.

  • Any borrowing above the 65% HELOC cap (up to the 80% combined limit) must be taken as an amortizing mortgage with scheduled payments, not revolving credit.

  • Lenders manage their risk by ensuring the average (/glossary/loan-to-value) (LTV) of their HELOCs is below their maximum stated limit.

Switching Mortgage Lenders at Renewal in Canada: 2026 Straight-Switch Guide (No Stress Test)

Related Questions

How does the stress test affect my 2026 renewal options?

Same-lender renewals and uninsured straight switches (OSFI, November 21, 2024) are exempt from the prescribed MQR. A refinance, an insured switch, or any increase in loan amount still requires the stress test — greater of 5.25% or contract + 2%.

What's the difference between insured and uninsured mortgage renewals?

Insured mortgages face stricter CMHC/Sagen constraints while uninsured mortgages enjoy flexible OSFI-only guidelines.

Should I consider switching lenders or negotiate with my current lender?

Your switching decision hinges on rate differential versus requalification risk, with break-even analysis determining optimal strategy.

When should I start my mortgage renewal process?

Start your renewal process 120-180 days before your current term expires to maximize your strategic options.

Under OSFI B-20, the HELOC portion of a combined mortgage is capped at 65% LTV; total borrowing (mortgage + HELOC) cannot exceed 80% LTV. Any amount above the 65% HELOC cap must be taken as an amortizing mortgage, not revolving credit.

OSFI Guideline B-20 sets two separate limits on combined mortgage–HELOC products. The revolving HELOC portion cannot exceed 65% of the property's value. The total of the amortizing mortgage plus the HELOC cannot exceed 80% LTV on an uninsured mortgage. If a borrower wants to access equity between the 65% HELOC cap and the 80% combined cap, the additional amount must be structured as an amortizing mortgage component with scheduled principal and interest payments — it cannot be drawn as revolving HELOC credit. Lenders must also confirm the borrower can service the combined debt and monitor credit behaviour on the HELOC portion.

The revolving HELOC portion is capped at 65% of your home's value under OSFI B-20; combined mortgage + HELOC cannot exceed 80% LTV.
