A line of credit typically offers a lower interest rate and a higher limit than a credit card, but a credit card provides an interest-free grace period if you pay the full balance each month. The better choice depends on whether you need ongoing, larger-sum borrowing or convenient short-term spending with rewards and purchase protection.
When you compare a line of credit vs credit card in Canada, the main differences come down to how interest is charged, how high the limit can go, and whether you get an interest-free grace period. Both are revolving credit products: you can borrow, repay, and borrow again up to a set limit. But they are built for different jobs.
| Feature | Line of credit | Credit card |
|---|---|---|
| Interest rate | Usually variable, often lower than a credit card; secured lines can be lower than unsecured. Rates vary by lender and province. | Often higher; can be fixed or variable. Rates vary by lender and card type. |
| Grace period | Generally no interest-free grace period. Interest starts accruing once you draw funds. | Many cards offer a grace period on purchases if you pay the full statement balance by the due date. Cash advances usually have no grace period. |
| Typical limit | Often larger, from a few thousand to tens of thousands of dollars; secured lines may be based on home equity. | Often smaller, though premium cards can have higher limits. Limits vary widely. |
| Security | Can be unsecured or secured (e.g., home equity line of credit). | Usually unsecured. |
| Best for | Debt consolidation, home renovations, large planned expenses, covering cash-flow gaps. | Everyday purchases, online shopping, rewards, short-term float, fraud protection. |
| Repayment | Minimum payment often interest-only or a small percentage of the balance; you can pay more. | Minimum payment is a percentage of the balance or a flat amount; paying only the minimum can keep you in debt longer. |
How interest works on a line of credit
A line of credit is a flexible loan. In Canada, most lines of credit use a variable interest rate tied to the lender's prime rate. For example, your rate might be expressed as prime plus a certain percentage. The Bank of Canada publishes policy interest rates that influence prime rates, though lenders set their own prime rates. Because the rate is variable, your interest cost can rise or fall with broader rate changes. Interest is usually calculated daily on the amount you owe and charged monthly. There is generally no interest-free period: if you draw $2,000 today, interest starts adding up right away. This makes a line of credit a poor choice for carrying a balance you could pay off within a month with a credit card's grace period, but a strong choice for borrowing you plan to repay over several months or years.
How interest works on a credit card
A credit card can be interest-free on purchases if you pay the full balance shown on your statement by the due date. That grace period is a real benefit: you might get 21 days or more of free financing, depending on the statement cycle. But if you carry a balance, interest applies—often at a much higher rate than a line of credit. Cash advances are different: they typically start charging interest immediately, with no grace period, and may carry a higher rate. The Financial Consumer Agency of Canada explains how credit cards, lines of credit, and other debts appear on your credit report, and how payment behaviour affects your credit score. Paying only the minimum on a high-interest card can stretch repayment for years.
Limits and access to credit
Lines of credit often come with higher limits than credit cards because lenders assess your income, assets, and credit history more deeply. A secured line of credit, such as a home equity line of credit (HELOC), may allow you to borrow against the equity in your home. The Financial Consumer Agency of Canada notes that loans and lines of credit have different features and costs, so it is important to read the agreement. Credit card limits, by contrast, are often set lower for new borrowers, though they can increase over time. A higher limit on either product is not free money—it is still debt. If you are applying with someone else, the FCAC's guidance on joint borrower disclosure explains what lenders must tell co-borrowers. Co-signing a line of credit or credit card can affect your own credit, so it helps to understand what a co-signer is before you agree.
When a line of credit is the better fit
A line of credit tends to work better when you need a larger sum, plan to repay over time, and want a lower interest rate. Common uses include consolidating high-interest credit card balances, covering a home renovation, paying for a large planned expense, or managing uneven cash flow as a contractor or small-business owner. Because interest is charged only on what you draw, you can leave the line unused and pay nothing. But be careful: a variable rate means your payment can change. If rates rise, more of your payment may go to interest. Also, many lines of credit require interest-only minimum payments, which can make the balance feel permanent if you do not deliberately pay down the principal. You can use a loan payment calculator to see how different repayment amounts affect the timeline.
When a credit card is the better fit
A credit card is usually better for everyday spending, online purchases, and short-term cash-flow timing. If you pay the statement balance in full each month, you get the grace period and pay no interest. Credit cards also offer practical protections: you can dispute unauthorized charges, and many cards include purchase protection, extended warranties, or rewards. For someone who needs to build or rebuild credit, responsible card use can help. But a credit card is a poor tool for long-term debt. If you cannot pay the full balance, the high interest rate can make the balance grow quickly. That is why carrying a balance on a credit card while having available room on a lower-rate line of credit is a common warning sign.

Rates, limits, and the fine print
Rates and limits vary by lender, province or territory, and your credit profile. Federal law sets a criminal interest rate ceiling of 35% per annum under the Criminal Code, section 347, and the Criminal Interest Rate Regulations. That ceiling does not mean every loan is affordable—it is a legal limit, not a recommended rate. For lines of credit, the rate may be prime plus a margin; for credit cards, the annual percentage rate is disclosed in your agreement. Always check the annual percentage rate (APR), how interest is calculated, whether there is an annual fee, and what happens if you miss a payment. The Financial Consumer Agency of Canada provides tools and information on loans and credit products. If a line of credit is secured by your home, the lender may have additional rights if you default, so the stakes are higher.
Common mistakes to avoid
- Using a credit card cash advance when a line of credit would cost less—cash advances often have no grace period and a higher rate.
- Paying only the minimum on a line of credit and never reducing the principal.
- Ignoring a variable rate: a small prime rate change can increase your monthly interest cost.
- Co-signing a credit card or line of credit without understanding that you are equally responsible for the debt.
- Treating a higher limit as extra income rather than borrowed money that must be repaid.
- Missing payments on either product, which can damage your credit score and lead to penalty rates or collection activity.
Who this suits
- A line of credit may suit you if: you need a larger sum, plan to repay over several months or years, want a lower rate, and can handle a variable rate.
- A credit card may suit you if: you pay your full balance each month, want rewards or purchase protection, and need convenient short-term spending.
- Both may suit you if: you use a card for daily purchases and keep a line of credit as a backup for larger planned expenses—but only if you have a repayment plan.
