Rates went up. An unchanged mortgage payment can still cost you.

Your mortgage payment can stay the same and your mortgage can still get more expensive. That is worth checking today, after the Bank of Canada raised its policy rate by a quarter of a percentage point to 2.50%.

The October 28 official announcement points to more persistent inflation and the risk that high energy costs spread into other prices. The Bank says further increases could be needed, while stressing uncertainty. That is a warning about risk, not a promise about the next decision.

For a GTA homeowner, the first call is to the lender, not the moving company. Find out what this decision changes in your actual loan before deciding whether you need to change anything else.

Same payment does not mean the same progress

There are different ways a mortgage absorbs a rate change. A fixed interest rate stays fixed during its term. With an adjustable payment variable mortgage, a change in your mortgage rate changes the payment. With a fixed payment variable mortgage, more of the payment can go to interest instead of the amount you borrowed. FCAC explains these differences in its mortgage interest guide.

Here is a simplified illustration, not a mortgage quote. Imagine a $3,200 payment currently covers $2,200 of interest and reduces the balance by $1,000. If interest takes another $125 while the payment stays at $3,200, only $875 goes toward the balance.

You have not lost $125 from this month's spending money. You have lost $125 of progress on the debt. Those are different problems, and the second one is easier to miss when you only look at your bank withdrawal.

Ask the lender for the balance projected at renewal before and after the change, using the same payment. That comparison is more informative than being told that your payment is unchanged.

Put the quarter point into dollars, carefully

Suppose your lender confirms that your own annual borrowing rate increases by 0.25 percentage points. On a constant $600,000 balance, $600,000 multiplied by 0.0025 is $1,500 a year, or about $125 a month in additional simple interest.

That is a rough measure of the interest exposure, not a calculation of your new mortgage payment. A real mortgage balance changes, interest calculation rules differ, and the payment also depends on the contract and repayment period. Do not add $125 to your payment and assume you have the lender's answer.

A household with a smaller mortgage but a large variable line of credit should check both accounts. On a constant $80,000 balance, the same assumed quarter point adds about $200 a year in simple interest. Debt outside the mortgage can matter to the move budget too.

Get these answers before choosing a fix

For a variable mortgage, ask when your lender's rate change takes effect, what your next payment will be, and how much of it will reduce the balance. Do not assume the policy rate is your mortgage rate or that every lender changes every product identically.

If your payment is fixed, ask how close you are to the point where it no longer covers the interest. FCAC's guidance on rising rates explains trigger rates, unpaid interest and why borrowers should speak to their lender early. Your agreement and lender determine your particular position.

Then ask for the cost of each option in writing. If you increase the payment, what balance would remain at renewal? If you convert to a fixed rate, what rate, term and fees apply? If you make a lump sum payment, how much is permitted without a penalty? A reassuring monthly number is not enough to compare those choices.

Buying or selling this fall?

If you are buying, take the actual property price, closing date, down payment and other debts back to your lender or licensed mortgage professional. Ask whether the financing you were relying on still works. Do that before removing a financing condition, not after you have committed to the purchase.

If you are selling and buying again, compare the two transactions together. A price reduction on the next house does not tell you the cost of carrying it. Put the net sale proceeds, any mortgage payout costs and the next home's confirmed payment on the same page.

Today's announcement does not tell us what a particular GTA house will sell for. It does give households a reason to replace an old borrowing assumption with a current written answer. Start there.
