A balance transfer sounds like a clean start. You move a high-interest credit card balance onto a new card charging 0% for a promotional period — sometimes up to 12 months — and eliminate the interest portion of your payment. No interest means more money to pay down the debt.
But there is a catch, and it catches a lot of people. The moment you use that card for everyday spending, the 0% advantage starts working against you.

How does a balance transfer card work in Canada?
A balance transfer card lets you move an outstanding balance from one or more existing cards onto a new card at a low introductory rate — sometimes as low as 0% — for a defined promotional period of time. In Canada, promotional periods typically run six to 12 months. A one-time transfer fee applies, usually 1% to 3% of the amount moved.
The math can be compelling. On a $5,000 balance at 19.99%, you would pay roughly $1,000 in interest over a year making only minimum payments. Move it to a 0% card with a 1% transfer fee, and that $50 fee is the only cost — provided you clear the balance before the promotional window closes.
Once that window closes, any remaining balance reverts to the card’s standard rate, which typically sits between 13.99% and 22.99%.

Why new spending on a balance transfer card backfires
The promotional rate applies only to the transferred balance — not to new purchases. Any new spending begins accruing interest immediately, which typically ranges from 12.99% to 22.99%.
For people trying to pay down debt, this poses a problem.
But there is a second problem: payment allocation. Under most cardholder agreements, if you pay more than the minimum, issuers apply the excess proportionately across all balance categories. So, a $400 payment on a card carrying $3,000 in transferred balance and $500 in new purchases does not simply eliminate the high-rate purchase balance first. A portion goes to each, leaving interest-accruing purchases on the card longer than expected.
The result? A card designed to cost nothing in interest starts quietly generating charges on the side. By the time the promotional period ends, the transferred balance may not be paid off — and the standard rate applies to everything.
What’s the right way to use a balance transfer card?
Treat it as a single-purpose debt-repayment instrument — not a card you carry in your wallet for daily use.
- Transfer the balance, then put the card in a drawer. Use your existing card or debit for everyday spending
- Calculate your required monthly payment before you transfer. Divide the full balance by the number of promotional months — on a $6,000 balance with a 10-month window, that’s $600 a month
- Set up automatic payments for at least the monthly target — missing one payment can trigger the loss of your promotional rate immediately under some cardholder agreements
- Don’t transfer more than you can realistically pay off. Clearing $4,000 entirely beats moving $8,000 and leaving $3,000 reverting to a 20%+ rate in month 13
- Keep your old card open but unused if it’s long-standing — closing it can push up your credit utilization ratio

Who is a balance transfer card best suited for?
A balance transfer card works best for someone with a specific, manageable balance they can pay off within the promotional window — generally someone with a credit score of approximately 660 or higher who can commit to not using the card for purchases during the repayment period.
For Canadians carrying serious or multiple types of debt, a non-profit credit counselling agency can help determine whether a balance transfer is the right tool or whether a broader debt management plan makes more sense. Credit Counselling Canada member agencies offer free confidential consultations.
A balance transfer card is one of the lowest-cost ways to buy time on high-interest debt — but only if it’s used as a one-purpose tool. The clock starts the moment you transfer. Every month you don’t spend on it and do pay it down is a month you keep money that would have gone to interest. That is the point. Don’t give it back.
