4-Year Fixed Mortgage Rate

A 4-year fixed mortgage rate is the interest rate on a closed mortgage whose rate stays unchanged for four years — a mid-length fixed term that sits between the popular 3-year and 5-year options. No single body publishes it. Lenders build it from their own cost of funds, anchored to Government of Canada bond yields of similar maturity, the prime rate, and expectations for the Bank of Canada policy interest rate, then add a spread for funding, credit risk, servicing, and margin.

How a 4-year fixed mortgage rate is determined

Fixed-rate mortgage pricing begins in the bond market. An investor who buys a Government of Canada bond is lending to the federal government for a set period at a set yield. Lenders fund fixed mortgages in a similar way, so the yield on Government of Canada bonds maturing near four years is a primary reference point. When those yields rise, fixed mortgage rates tend to rise; when they fall, fixed rates tend to follow, though not always immediately or by the same amount.

The Bank of Canada policy interest rate sits further back in the chain. It sets the overnight cost of short-term money, which shapes the prime rate that banks publish and use for variable-rate mortgages and lines of credit. The policy rate does not set fixed mortgage rates directly, but it influences the wider interest-rate environment and the market's expectations for inflation and growth, and those expectations feed into bond yields. A separate guide to how mortgage rates work in Canada sets out that chain in more detail.

Lenders publish a posted rate and then apply a discounted rate to most borrowers, so the figure on a bank's website is rarely the rate a well-qualified borrower is offered. The size of that discount moves with competition, funding conditions, and the borrower's profile. A four-year fixed term also carries a term premium: in a normal market, lending money for longer means a higher yield than lending for a shorter period, and the gap between a 3-year and a 4-year fixed rate partly reflects that extra time.

The Bank of Canada publishes a conventional mortgage rate series covering posted rates at chartered banks for residential mortgages. It surveys advertised rates rather than the negotiated rates borrowers actually sign. Check the current figure and the methodology at the source.

Who a 4-year fixed term typically suits

A four-year fixed term suits borrowers who want a payment that will not change for a defined period but who are not ready to commit for five years. It often appeals to buyers who expect their circumstances to shift — a relocation, a renovation, a growing family, or a plan to sell — and who want the mortgage term to end around the same time as that event. Matching the term to a known milestone means the renewal decision arrives when it is actually useful.

It can also suit borrowers weighing the cost of breaking a mortgage. A shorter fixed term means fewer years of interest-rate exposure, and while the penalty formula itself does not change with term length, the interest rate differential on a shorter remaining term is often smaller because less time is left. Borrowers who expect to refinance or move early sometimes accept a different rate in exchange for that flexibility.

How a 4-year fixed term compares with 3-year and 5-year terms

All three terms are priced from different points on the same yield curve.

No term is cheapest in every market. When the yield curve is steep, the gap between adjacent fixed terms is wider; when it is flat or inverted, a longer term can price close to a shorter one. Compare the discounted rates actually offered to you and the total cost over the term, not posted figures alone.

Renewal, breaking early, and prepayment

At the end of a four-year fixed term the mortgage matures. If the balance is not paid off, the borrower either renews with the existing lender or switches to another. Renewing at maturity normally does not trigger a prepayment penalty, but it resets the rate to whatever the lender offers at that time, so the renewal offer is worth comparing against other lenders before signing.

Breaking a closed fixed mortgage before maturity usually triggers a prepayment penalty. For fixed-rate closed mortgages the penalty is commonly the greater of three months' interest or the interest rate differential, calculated on the remaining balance and the time left in the term. The exact formula, and whether the lender uses the posted rate or the discounted rate in it, is set out in the mortgage contract and can differ widely between lenders. The penalty for breaking a mortgage early is worth understanding before you sign.

Many closed mortgages also include a prepayment privilege that lets a borrower pay down a set portion of the principal each year, or increase regular payments, without a penalty. The size and mechanics of the privilege vary by lender and product. Where lump-sum payments are likely, the privilege can matter as much as the rate. A mortgage payment calculator can show how extra payments shorten the amortization.

What to check before choosing a 4-year fixed term

• Confirm whether the quoted rate is the discounted rate, and ask what it is discounted from.
• Read the prepayment penalty clause and the exact formula used for closed fixed-rate mortgages.
• Check whether the mortgage is portable or assumable if a move is possible.
• Ask about prepayment privileges and whether the allowance resets each year.
• Confirm whether the charge is a standard charge or a collateral charge, since this affects how easily the mortgage can be switched at renewal.
• Check the length of the rate hold and what happens if the closing date is delayed.
• Ask what qualification rate the lender will use under the federal mortgage stress test.

Under the federal stress test, federally regulated lenders must qualify borrowers at a rate above the contract rate — typically the greater of the contract rate plus a buffer set by the regulator, or a published floor rate. Both figures are policy settings that change over time; confirm the current values with OSFI or the Financial Consumer Agency of Canada. Meeting the stress test does not guarantee approval, and lenders still apply their own credit, income, and property criteria.
