The Best Mortgage Rate in Canada

The Best Mortgage Rate in Canada

The rate advertised in a bank window and the rate written into your contract are rarely the same number. Between the two sit a qualifying test, debt service ratios, a down payment, a term, an amortization and a penalty clause almost nobody reads.

One marker, with a date attached: on September 2, 2026, the Bank of Canada held its policy rate at 2.25%. That rate moves, and mortgage rates move with it. Any rate figure you read in an article ages quickly, so check the date before you rely on it.

I am a real estate broker, not a lender or a mortgage broker. This is general information drawn from the public sources named in the text.

The posted rate and the discounted rate

The Financial Consumer Agency of Canada puts it plainly: the posted rate is the rate lenders advertise for their products, and a discounted rate is lower than the lender’s posted rate. The agency adds a line worth taking literally: ask your lender if they can offer you a discounted rate.

Remember the posted rate for a second reason. It comes back in the calculation of your penalty if you break the contract before the end of the term.

What the lender calculates before quoting a rate

The stress test. The Office of the Superintendent of Financial Institutions sets a minimum qualifying rate for uninsured mortgages: the greater of the mortgage contract rate plus 2% or 5.25%. You do not borrow at that rate. You only have to show you could carry it. FCAC states the same rule on the buyer’s side.

The debt service ratios. CMHC caps an insured loan at two levels: 39% gross debt service, which adds principal, interest, taxes and heat against gross income, and 44% total debt service, which adds your other debts. FCAC uses the same thresholds.

Credit. For a CMHC insured loan, at least one borrower or guarantor needs a credit score of at least 600. See what your credit score actually changes, then run your own numbers through the affordability calculator.

Fixed or variable

A fixed rate stays the same for the whole term. FCAC notes it is usually higher than a variable rate: you pay a premium for payment certainty.

A variable rate follows the lender’s prime rate, quoted as prime plus or minus a spread. When rates rise, more of each payment goes to interest. And depending on the product, the payment itself can move: with an adjustable payment, the amount withdrawn changes when the rate changes.

Nobody can tell you where rates are going. The real question is your margin. If a payment increase would put you in difficulty, certainty is worth its price.

Term is not amortization

The term is the length of the contract you sign with that lender. At the end you renew, with them or elsewhere. FCAC observes that lenders often quote a higher rate for a longer term, though not as a rule.

Amortization is the total time planned to repay. For an insured loan, CMHC caps amortization at 25 years under its CMHC Purchase product. Its CMHC Home Start product allows 30 years, with a premium surcharge of 0.20 point, when at least one borrower is a first-time buyer or the home is newly built and never occupied, for a value under $1,500,000.

Stretching the amortization lowers the monthly payment and raises the total interest paid. A mortgage calculator makes both effects visible in seconds.

On the down payment, under federal rules, as explained by FCAC, the minimum is 5% up to $500,000, then 10% on the portion above that, and 20% from $1.5 million. Below 20%, mortgage loan insurance is required. See also the 20% down payment myth.

The penalty nobody looks at when signing

Break a closed contract before the end of the term and you pay a prepayment penalty. According to FCAC, it is generally the higher of two amounts: three months’ interest on what you still owe, or the interest rate differential.

The differential compares two rates. The first is either the posted rate at the time you signed or your current or discounted rate. The second is either the current posted rate for a term of similar length or that same rate minus the discount you were originally given. The result then depends on the amount you prepay, the months left in the term, current rates and your lender’s method.

This is where two contracts at the same rate stop being equivalent. Federally regulated institutions must tell you how they calculate the penalty and what factors they use, in language that is clear, simple and not misleading. The federal code of conduct goes further: annual information on your prepayment privileges, the amount allowed each year and the calculation method, then, once you confirm your intention to prepay, a written statement giving the applicable charge and how it was calculated.

Ask for the method in writing before you sign, not on the day you sell.

Federal bank or caisse: two supervisors

OSFI supervises federally regulated institutions, and its minimum qualifying rate applies to their uninsured loans. It allows an exception for a straight switch at renewal to another federal lender, with no increase in the loan amount or the amortization period.

In Quebec, financial services cooperatives answer instead to the Autorité des marchés financiers, which publishes its own guideline on residential mortgage lending, applying to cooperatives, trust companies and other authorized deposit institutions.

The practical consequence: the market is not limited to the big banks, and two lenders read the same file differently.

The mortgage broker in Quebec

Since May 1, 2020, oversight of mortgage brokerage has sat with the AMF, under the Act respecting the distribution of financial products and services. Before that date it belonged to the OACIQ.

Two moves before you hire anyone: check the certificate in the AMF register, and ask how the broker is paid and how many lenders were actually approached for you.

Why the lowest rate is not always the best contract

Four things weigh as much as the third decimal of the rate.

A lower rate paired with thin privileges and a penalty computed off the posted rate can cost more than a slightly higher rate on a flexible contract. The question is not which number is smallest today. It is what the contract costs you over the whole term, including the exit you did not plan for: a sale, a separation, a job in another city, a refinancing to fund work on the house.

The method, in four moves

  1. Run the math at the minimum qualifying rate first, not at the rate you hope for.
  2. Ask every lender three things, in writing: the rate, the penalty method and the prepayment privileges.
  3. Date every quote, because a rate offer has a shelf life.
  4. Build the file before you shop. That is the point of the first-time buyer mortgage guide and of the pre-approval mistakes.

If this is a first purchase, check the tax benefits you are entitled to as well. They move your budget more than a tenth of a point of rate.
