How Credit Card Balance Transfers Work in Canada

A credit card balance transfer moves debt from one card to another, usually to take advantage of a lower promotional interest rate.

Many Canadians start looking into balance transfers when credit card debt gets expensive to carry. NerdWallet Canada’s 2026 Canadian Consumer Credit Card Report found that 19% of Gen Z Canadians said they had applied for a balance transfer offer in the previous 12 months. And with many Canadian credit cards charging interest rates around 19.99% to 20.99%, carrying a balance from month to month can get expensive fast.

A balance transfer can be a useful debt-payoff tool if it lowers your interest costs and gives you time to make real progress. But it’s not automatic debt relief. If you don’t understand the fees, timing and repayment rules — or you can’t pay the balance down during the low-rate period — you could end up right back where you started.

Step 1: Apply for a balance transfer card

Start by comparing balance transfer credit cards to find one that fits your situation.

Look at more than just the headline promotional rate. You’ll also want to compare the regular interest rate, the length of the promotional period, any balance transfer fee, and whether the card charges an annual fee.

Make sure you qualify for the card and that it accepts the kind of transfer you want to make. You may need to apply for a card from a different issuer, since most lenders don’t allow transfers from their own credit products.

Once you’ve chosen a card, apply and wait for approval. Some issuers let you request the balance transfer during the application process, so it can help to have your existing account information and transfer amount ready.

Step 2: Transfer the balance

After you receive your new card, you can request the balance transfer.

Depending on the issuer, you may be able to do this online, by phone or as part of the application process.

It’s important not to assume the transfer happens instantly. Until the transfer is fully processed and you’ve confirmed the old balance has been paid off, keep making at least the minimum payment on your original card. Missing a payment while the transfer is still in progress could lead to interest charges or a hit to your credit score.

In addition to the amount you transfer, you may also have to pay a balance transfer fee. These fees are often charged as a percentage of the amount transferred, though some promotional offers waive them entirely.

Fees of 1% to 3% are common, but they can be higher in some cases, especially outside promotional offers. For example, transferring $1,000 with a 2% balance transfer fee would add $20 to your balance.

Step 3: Pay down your credit card balance

Once the transfer is complete, the real work begins: paying off the balance before the promotional rate ends.

Let’s say you transfer a $1,000 balance and pay a 2% balance transfer fee. Your new balance is $1,020. If your card offers 0% interest for six months, you’d need to pay $170 per month to clear the balance before the promo expires.

This is where a balance transfer either helps — or just delays the problem. If you can repay the balance within the low-rate period, you may save a meaningful amount in interest. If you still have a large balance left when the promo ends, whatever remains could start accruing interest at the card’s regular rate.

Setting up automatic payments or pre-authorized debits can help you stay on track. It’s also smart to build those payments into your budget before you initiate the transfer.

Once you transfer your balance, it’s usually best to stop using that card for new purchases. The promotional rate may apply only to the transferred balance, not to anything new you charge. That means new purchases could start accruing interest right away if you don’t pay your full statement balance.

On top of that, your payments may not be applied the way you expect, which can make the debt harder to clear.

A balance transfer can be worth it if it cuts your interest costs enough to help you get out of debt faster.

That said, balance transfers also take time, may involve fees, and usually require a new credit card application, which triggers a hard credit inquiry. The best balance transfer offers are often reserved for applicants with good or excellent credit, and you’ll need a high enough credit limit to cover the amount you want to transfer, plus any applicable fee.

If your credit is weaker, you may still qualify for a card — but not necessarily one with a low enough rate or high enough limit to make the transfer worthwhile.

The real question is not whether you can move the debt. It’s whether you can actually pay it down before the promotional rate ends. A balance transfer usually works best when the amount is manageable enough to repay most or all of it during the intro period. Otherwise, you may just be moving debt around instead of reducing it.

That may be easier said than done: among Canadians with credit card debt, 45% said it would take them six months or longer to pay it off, according to NerdWallet Canada’s 2025 Canadian Consumer Credit Card Report.

A simple way to think about it: compare the transfer fee and any likely post-promo interest with the interest you’d pay if you stayed where you are. If the transfer doesn’t leave you clearly better off, another option for consolidating your credit card debt may be a better fit.

A balance transfer can affect your credit score, but the impact is usually temporary if you manage the new card well.

Here are a few ways your credit could take a temporary hit:

Applying for too much credit at once

A balance transfer card application triggers a hard credit check. If you apply for several cards or loans within a short period, your score may dip for a while.

Continuing to carry balances on multiple cards

If you transfer a balance but keep using your old cards or add new debt elsewhere, your credit utilization ratio can stay high, which may hurt your score.

Closing your old card too quickly

After transferring the balance, you might want to close the old card and move on. But if that card has no annual fee, keeping it open may help your credit by preserving available credit and the age of your accounts. Closing it could reduce your total available credit and push your utilization higher.

Not all balance transfer cards work the same way, so it’s important to look beyond the advertised promotional rate.

Some cards offer 0% interest for a limited time, while others offer a low ongoing rate instead. Some charge no annual fee, while others may still be worth considering if the savings from the lower rate outweigh the cost of carrying the card.

You’ll also want to check whether a balance transfer fee applies, how long the promotional rate lasts, and what interest rate kicks in afterward. If you’re likely to carry the balance beyond the intro period, those details matter just as much as the promo itself.

The right balance transfer card is one that gives you enough time and enough savings to make real progress on your debt. If all it does is move the balance to a new home, it probably isn’t solving much.
