A line of credit and a credit card are both revolving credit, but they serve completely different purposes. Use a credit card for everyday spending (and pay it off monthly to earn rewards interest-free). Use a line of credit only when you need to borrow money, because the interest rate is half or less of a credit card’s. The most expensive mistake Canadians make is carrying a balance on a 19.99% credit card when they could have that same balance on a 7–12% line of credit. The second most expensive mistake is using a line of credit for daily spending and missing out on rewards and purchase protection.

Interest Rate Comparison
The interest rate gap between lines of credit and credit cards is the single biggest reason to care about this comparison. On a $5,000 balance, a line of credit at 9% costs $450/year in interest; a standard credit card at 19.99% costs $1,000. That’s $550 in pure savings for moving the same debt to a cheaper product. However, lines of credit don’t have a grace period — interest starts accruing the day you use the money. Credit cards give you 21+ days interest-free if you pay the full balance each statement period. This is why the optimal strategy is to use a credit card for purchases you can pay in full and a line of credit only when you genuinely need to borrow.

Having Both
The ideal setup for most Canadians is a cashback or rewards credit card for all everyday spending (paid in full each month) plus a personal line of credit as an emergency fund backup. The credit card earns you 1–5% on every purchase, and the line of credit sits unused until you have a genuine need to borrow. If you ever do carry a credit card balance accidentally, transfer it to the line of credit immediately to cut your interest cost in half. This two-product strategy gives you the best of both worlds: rewards on spending and low rates on borrowing.

The Bottom Line
Use a credit card for spending, a line of credit for borrowing. Never carry a balance on a credit card if you have access to a line of credit at half the rate. And if you can pay your credit card in full each month, the grace period gives you interest-free spending plus rewards — something no line of credit can match.
