Mortgage Renewal: how not to overpay when renewing your mortgage

Mortgage renewal is not a formality and not just a signature on the letter your bank sends you. For many Canadian homeowners, it is one of the most important financial moments in the entire period of owning a property. This is the point at which you may save thousands of dollars, improve the terms of your loan, reconsider amortization, consolidate debts - or, on the contrary, make an expensive mistake by automatically accepting the first offer.

In recent years, renewal has become especially sensitive. Many mortgages coming up for renewal were originally taken during a period of historically low interest rates, when the Bank of Canada policy rate was near zero or far below today’s levels. For many homeowners, a new term therefore means not just updated paperwork, but a confrontation with higher monthly payments and the need to reassess the family budget.

According to CMHC, about 1.2 million fixed-rate mortgages were coming up for renewal in 2025, and more than 85% of them had been contracted when the Bank of Canada policy rate was 1% or lower. This means that many borrowers are moving from the era of cheap money into a very different reality. Even though rates have already come down from their peak levels, they remain meaningfully higher than they were during the pandemic.

The good news is that after a sharp cycle of rate increases, the Bank of Canada began cutting its policy rate. By the end of 2024, it had been lowered to 3.25%, and in the following period it moved lower still. But it is important to understand that even lower rates do not return the market to the conditions of 2020-2021. For a homeowner, this means one thing: renewal must be prepared in advance, calculated carefully and compared properly, rather than assuming your current bank will automatically offer the best solution.

Why you should not automatically sign the bank’s offer

Banks know very well that many clients choose the easiest path. A few months before the end of the term, they receive a renewal letter, see several rate options, select one, sign and send it back. Fast. Convenient. No extra conversations. But this convenience can be expensive.

Your current bank is not obligated to offer you the best rate on the market. Its goal is to keep the client on terms that are favourable to the bank. In the past, many borrowers with uninsured mortgages were effectively “locked in” with their lender, because switching to another bank required them to pass the stress test again. If income, debts or rates made qualification difficult, the borrower often stayed where they were, even when the offer was weak.

Since November 21, 2024, the rules have become more favourable for consumers: OSFI removed the stress test requirement for uninsured borrowers making a straight switch at renewal from one federally regulated lender to another, without increasing the loan amount and without extending amortization. A similar advantage had already existed for insured mortgages. This important change strengthened competition between banks and gave many homeowners more freedom at renewal.

There is an important clarification, however. If you want to increase the mortgage amount, change amortization, take equity out, consolidate debts or substantially change the structure of the loan, that is no longer a simple straight switch. In such cases, qualification, the stress test and lender requirements may apply differently. That is why it is important to understand in advance what exactly you want to do: simply move to a better rate or use renewal as an opportunity to restructure your entire financial picture.

Renewal is a chance to reconsider the strategy

For some clients, the smartest option may indeed be simple: choose a good rate, keep the mortgage structure and continue making payments. But for many people, renewal is a chance to do more.

Your life may have changed over the past several years. Income may have increased or decreased. Children may have arrived. Expenses may have grown. Credit card debts, a line of credit, a car loan or renovation costs may have accumulated. Perhaps you are thinking about renovating, buying an investment property, helping children, planning for retirement or consolidating debts. In that situation, renewal is the perfect moment not simply to update the rate, but to look at the entire household balance sheet.

Sometimes it makes sense to consider debt consolidation through refinancing, especially if expensive unsecured debts are creating heavy pressure. Sometimes it is better to keep the current mortgage amount and not stretch consumer debts over decades. Sometimes a shorter term makes sense for flexibility, while in other cases a fixed rate is better for peace of mind. There is no universal answer. There is only proper analysis of a specific family’s situation.

Fixed or variable: what to choose

After a period of high rates, many clients have again become interested in variable and adjustable mortgages. The logic is understandable: if the Bank of Canada is cutting the policy rate, a floating rate may gradually become more attractive. But that does not mean variable is right for everyone.

A variable rate may be a reasonable option for clients with stable income, strong cash flow, a low level of stress around payment changes and a willingness to accept uncertainty. If rates continue to decline, such a borrower may benefit. But if inflation rises again, the economy changes or rate cuts stop, payments may remain higher than expected.

A fixed rate is better suited to those who value predictability. Yes, a fixed mortgage may prove more expensive in a scenario where rates continue to fall, but it provides peace of mind: you know your payment, you can plan your budget and you are not dependent on every central bank decision. For a family with a tight budget, this may matter more than potential savings.

The main mistake is choosing the rate as if it existed separately from life. A mortgage is not only an interest rate. It is your cash flow, risk, job, children, plans, emergency fund, retirement and ability to withstand a bad scenario.

Do your own stress test

The official stress test is a banking formula. But every family should have its own personal stress test. That one is far more important.

Ask yourself: what happens if rates are higher a few years from now than they are today? What happens if one spouse temporarily loses a job? What happens if you go on maternity or parental leave? What happens if home maintenance, insurance, property tax, condo fees or utilities rise again? What happens if you decide to retire earlier than planned?

An experienced mortgage broker can help not only to find a rate, but to test the strength of the entire financial structure. Sometimes the lowest rate is not the best product. Sometimes prepayment privileges, portability, penalty structure, refinancing ability, mortgage type, the cost of breaking the term and flexibility matter more. These details often become decisive when life does not go according to plan.

What to do 4-6 months before renewal

If your mortgage is coming up for renewal in the next 4-6 months, do not wait until the last week. Start early. Gather information about your current mortgage: maturity date, balance, rate, payment, amortization, prepayment options, type of charge, penalty terms and renewal offer, if the bank has already sent one.

Then compare your options. Do not limit yourself to the letter from your current bank. Check offers from other lenders, straight switch conditions, the possibility of getting a better rate, and refinance or debt consolidation scenarios if you truly need them. If you are self-employed, recently changed jobs, have a high debt ratio or have a non-standard situation, you will need even more time.

It is also important to check your credit history in advance. An error on the credit report, a forgotten debt, high utilization on credit cards or recent missed payments can worsen the terms offered to you. It is better to discover this before you begin negotiations with lenders.

The main conclusion

Mortgage renewal is a moment when passivity almost always works against the homeowner. Signing the first offer is easy, but not always wise. In an environment where rates are changing, switching rules between lenders have become more flexible and family budgets are under pressure, renewal should be treated as a financial review of your entire homeownership strategy.

If your mortgage is coming up for renewal, do not automatically stay with your current bank and do not accept any rate they send you. Speak with a professional mortgage broker, compare the available options, check your qualification and make the decision based on numbers, not haste.

The right renewal can save money, reduce stress, improve your debt structure and give your family more financial stability. The wrong one can lock in overpayment for years. The difference between these two scenarios often begins with one simple action: do not sign automatically - check the market first.
