Fixed vs Variable Rate Mortgage in Canada: How to Choose

Current Mortgage Rates from Canada's Big Six Banks (2026)

As of mid-2026, indicative 5-year fixed rates at Canada's major lenders range from approximately 4.49% at TD Bank and RBC to 4.59% at BMO and Scotiabank, with CIBC and National Bank sitting near 4.54%. These are posted rates; many borrowers negotiate discounts of 20 to 50 basis points through a mortgage broker or by leveraging existing banking relationships. Always request the effective rate in writing before committing.

Variable-rate mortgages are currently priced as a spread relative to each lender's prime rate, which itself tracks the Bank of Canada overnight rate closely. TD, RBC, Scotiabank, and BMO are offering variable rates in the range of Prime minus 0.50% to Prime minus 0.90%, translating to roughly 4.20% to 4.60% depending on the lender and your credit profile. National Bank and CIBC sit at similar spreads, though their prime-rate definitions can differ slightly from the Big Four.

Short-term fixed options — 2-year and 3-year terms — are attracting attention from borrowers who believe the Bank of Canada may continue easing, making a shorter commitment strategically appealing. Two-year fixed rates are currently around 4.75% to 5.10%, reflecting the inverted yield curve environment. Comparing across lenders is essential: even a 0.20% difference on a C$500,000 mortgage over five years represents more than C$5,000 in interest costs.

Fixed Rate vs Variable Rate Mortgages: Which Is Right for You?

A fixed-rate mortgage locks your interest rate and monthly payment for the entire term — typically 1 to 5 years in Canada, though 7- and 10-year terms exist. This predictability is ideal for buyers on tight budgets, those with lower risk tolerance, or anyone purchasing in a high-rate environment who wants to protect against further increases. The trade-off is that if rates fall significantly, you are locked in unless you break the mortgage, which can trigger substantial prepayment penalties — often calculated as three months' interest or the interest rate differential (IRD), whichever is higher.

Variable-rate mortgages in Canada come in two main flavours: adjustable-rate mortgages (ARMs), where the actual payment amount changes with the prime rate, and variable-rate mortgages with fixed payments, where the amortization period adjusts instead. When the Bank of Canada cut its overnight rate through 2024 and into 2025, variable-rate holders with ARMs saw their payments fall immediately, while those with fixed-payment variables saw more of each payment go toward principal. Understanding which product you hold is critical during a rate cycle.

Historically, Canadian borrowers who stayed in variable-rate mortgages over long periods paid less interest than those in fixed-rate products, but the 2022-2023 rate hiking cycle reminded the market that past performance is not guaranteed. Your decision should factor in your job security, household cash-flow flexibility, how close you are to mortgage renewal, and your view on the Bank of Canada's rate trajectory. A mortgage broker licensed under your provincial regulator can model both scenarios using your actual numbers.

How the Bank of Canada Overnight Rate Affects Your Mortgage

The Bank of Canada sets the overnight rate — the interest rate at which major financial institutions borrow and lend one-day funds — through its eight scheduled policy announcements per year. When the BoC raises this rate, Canadian banks typically increase their prime rate by the same amount within days, directly raising the cost of variable-rate and home equity line of credit (HELOC) borrowing. Fixed mortgage rates, by contrast, are more closely tied to Government of Canada bond yields, particularly the 5-year benchmark bond, which can move independently of BoC policy depending on global investor sentiment.

After a rapid hiking cycle that took the overnight rate from 0.25% in early 2022 to 5.00% by mid-2023, the Bank of Canada pivoted to cutting rates through 2024 and 2025. As of 2026, the overnight rate sits at a level that continues to influence the spread between fixed and variable products. Borrowers with variable mortgages have directly benefited from each 25-basis-point cut, while fixed-rate renewal borrowers are experiencing payment shock as they roll off historically low pandemic-era rates into the current environment.

FCAC (Financial Consumer Agency of Canada) and the BoC both publish educational resources explaining how rate changes flow through to consumer mortgage costs. OSFI also monitors systemic risk arising from heavily indebted variable-rate borrowers, and its guidelines require lenders to stress-test affordability at qualifying rates well above contract rates — a safeguard designed to prevent payment shock from causing widespread defaults during rate-hiking cycles.

The OSFI Stress Test and Qualifying for a Mortgage in Canada

Canada's mortgage stress test, governed by OSFI's B-20 Guideline for federally regulated lenders, requires all applicants — whether buying with a large down payment or a small one — to prove they can afford their mortgage at the higher of their contract rate plus 2 percentage points, or the floor rate of 5.25%. This means a borrower offered a 4.50% variable rate must qualify as if paying 6.50%. The rule applies at TD, RBC, BMO, Scotiabank, CIBC, and National Bank, as well as most credit unions subject to provincial equivalents.

The stress test is applied when you first take out a mortgage, when you renew with a new lender (though OSFI introduced a limited exemption for straight renewals with the same lender in 2023), and when you refinance or increase your mortgage amount. First-time buyers are often surprised to find that their pre-approval amount is significantly lower than what they expected based on current rates alone. Working with a mortgage professional to understand your total debt service (TDS) ratio — which must generally remain below 44% — is a crucial step before making an offer on a property.

OSFI also regulates lender capital requirements and underwriting standards through broader guidelines that apply to all institutions under federal charter, including the Big Six banks. Provincial credit unions fall under provincial regulators but often mirror federal stress-test rules voluntarily. CDIC (Canada Deposit Insurance Corporation) protects eligible deposits at member institutions up to C$100,000 per category, though mortgage products themselves are not deposit instruments — CDIC coverage is relevant when your down payment savings are held at a CDIC member institution.

CMHC Mortgage Insurance and Extended Amortization

Canada Mortgage and Housing Corporation (CMHC) mortgage insurance is required for any home purchase where the buyer's down payment is less than 20% of the purchase price. The premium — paid by the borrower but protecting the lender — ranges from 0.60% to 4.00% of the mortgage amount, depending on the loan-to-value ratio. On a C$500,000 insured mortgage with a 5% down payment (C$25,000), the CMHC premium would be 4.00%, adding C$19,000 to the mortgage balance. This premium is subject to provincial sales tax in some provinces and cannot be rolled into the mortgage in those cases.

A significant policy change that took effect in late 2024 allows insured mortgages — those with down payments under 20% — to be amortized over up to 30 years, up from the previous 25-year maximum. This extends to first-time buyers purchasing any property and to all buyers purchasing a newly built home. The longer amortization reduces monthly payments, improving affordability, though it also means paying significantly more in total interest over the life of the mortgage. Buyers should use a Canadian mortgage calculator to compare their 25-year vs 30-year payment and total interest scenarios before deciding.

Private mortgage insurers Sagen (formerly Genworth Canada) and Canada Guaranty compete with CMHC and offer similar premium structures. All three insurers are regulated under federal statute, and their products are accepted by all major Canadian lenders. If your home purchase price exceeds C$1.5 million, mortgage insurance is not available, meaning a minimum 20% down payment is mandatory regardless of your financial profile.

First-Time Homebuyer Programs: FHSA, RRSP Home Buyers' Plan, and First Home Buyer Incentive

Canada's First Home Savings Account (FHSA), introduced in 2023, allows first-time buyers to contribute up to C$8,000 per year — and carry forward unused room — to a lifetime maximum of C$40,000. Contributions are tax-deductible (like an RRSP), and qualifying withdrawals for a first home purchase are completely tax-free (like a TFSA). Combining the FHSA with the RRSP Home Buyers' Plan, which allows a withdrawal of up to C$35,000 per person (or C$70,000 for a couple) tax-free with repayment over 15 years, gives first-time buyers a powerful savings and tax advantage that can meaningfully reduce the mortgage they need to carry.

The First Home Buyer Incentive, a shared-equity program administered by CMHC, offered 5% or 10% of a home's purchase price as an interest-free loan in exchange for a proportional equity stake in the property. The federal government announced the winding down of this program in 2024 due to lower-than-expected uptake, though buyers who entered the program continue to hold their agreements. First-time buyers in 2026 should focus primarily on the FHSA, the Home Buyers' Plan, the First-Time Home Buyers' Tax Credit (worth up to C$1,500 in federal tax relief), and the GST/HST New Housing Rebate for newly constructed homes, which can return a significant portion of the tax paid on a qualifying new build.
