In Canada, the terms credit card and line of credit are sometimes mistaken for one another. Though they both are associated with a third party lending money to borrowers, but they have their differences.
A line of credit lets you borrow money up to a certain limit and pay it back over time. You don't have to pay it all back at once, just a minimum amount each month. If you take longer to pay back the rest, it might affect your credit score. A credit card works a bit differently. It gives you a set amount of money to use each month. You need to pay back what you spend every month, or at least make a minimum payment and carry the rest to the next month. Basically, all credit cards are a type of line of credit, but not all lines of credit come with a credit card.
Credit card and line of credit differs in most aspects which is why it is important to know the differences. Let me walk you through all these differences in detail to give you an in-depth understanding.
Here are some of the major points on credit card vs line of credit:
Lines of Credit: Primarily used for significant expenditures or ongoing expenses. They offer a high degree of flexibility in terms of how much and when you borrow within your credit limit. This makes them suitable for larger or unexpected costs, such as home renovations, education, or consolidating high-interest debts.
Credit Cards: Ideal for everyday purchases, online shopping, and smaller expenses. They are widely accepted as a payment method globally, providing convenience and immediacy in transactions. Credit cards often come with added benefits such as rewards programs, cashback, travel perks, and consumer protection features.
The APR or annual percentage rate applied to credit cards and lines of credit also varies considerably.
Lines of Credit: Generally have lower APRs compared to credit cards. The interest rates are often variable and may fluctuate with the prime rate. This makes them more cost-effective for long-term borrowing.
Credit Cards: Typically have higher APRs, especially for carried balances beyond the payment due date. Some credit cards offer promotional low or 0% interest rates for a limited period, but the rates can significantly increase after the promotional period.

Lines of Credit: Often provide higher credit limits, sometimes reaching substantial amounts depending on the borrower’s creditworthiness and financial status. This high limit can be beneficial for covering larger expenses.
Credit Cards: Usually offer lower credit limits in comparison to lines of credit. The limit is set based on several factors, including credit score, income, and existing debt.
Lines of Credit: Designed for users who need access to a larger amount of funds and prefer the flexibility of borrowing and repaying over time. They are not typically used for day-to-day purchases but for more substantial financial needs.
Credit Cards: Aimed at providing a convenient way to manage daily expenses, with the added advantage of rewards and benefits. They are not typically used for large-scale borrowing due to higher interest rates.
Both offer revolving credit facilities. This means you can borrow, repay, and borrow again up to your credit limit. The key difference lies in how they are used and the cost associated with each.
For credit cards, when you purchase using the card and receive the bill at the end of the month you can choose to pay the balance in full or pay the minimum amount due and revolve the rest of the balance This way you can move some debt to the next billing cycle and can still enjoy the benefits of the credit card. For instance, your credit limit is $2000 and your month-end bill is $700. You can choose to pay the minimum amount due and take the rest of the amount to the next month (by agreeing to pay interest rate on the amount you carry).
For the line of credit, every user has a credit limit up to which they can borrow. The user can take the loan using the line of credit, repay it, and then take the loan again at a later time. For instance, your credit limit is $3000. You took $2500 for your home renovation in January and repaid that loan by July. Meanwhile, you needed a loan for your car maintenance and you withdrew $500 in August. Note that you will need to pay interest on this amount every month that it is borrowed.
Credit cards are well known for the rewards and benefits they offer. These perks can be quite attractive and often include cashback, free miles, redeemable reward points, discounts, and other incentives that motivate users to apply for them. Therefore, if you're making a purchase you can pay off in full, using one of the best rewards credit cards available is definitely a smarter choice.
However, a line of credit doesn’t have any such associated reward or benefit system. Though it doesn’t excite users to have no rewards and benefits plan at the same time it is a relief for those who get tempted to overspend just to get a reward they are trying to achieve. With no rewards to follow, the users of the line of credit have nothing to worry about.
The documentation required for a line of credit is quite extensive in comparison to the documents necessary for the application process of a credit card. It is because, in line of credit, the lender is extending access to hefty funds for which they need the assurance that the financial condition of the user is good enough to pay back the borrowed debt. This is why the application process for a line of credit requires more time and scrutiny in comparison to the application process for a credit card.
One of the biggest financial advantages of a line of credit is its usefulness in paying down existing credit card debt. Since most credit cards carry significantly higher interest rates than lines of credit, transferring or paying off your card balance using a line of credit can immediately lower your monthly interest costs. This means more of your payment goes toward the principal instead of interest, helping you get out of debt faster.

The reason this strategy is so effective is because of the difference in APR. Credit cards commonly charge interest rates ranging from 19% to 24% or higher, especially on revolving balances. Lines of credit, on the other hand, typically have much lower variable interest rates tied to the prime rate. For borrowers who qualify, this is a much more cost-efficient way to manage existing debt, without resorting to high-interest minimum payments that barely reduce the balance.
Additionally, a line of credit doesn’t lock you into a fixed repayment structure the way a traditional consolidation loan does. You can repay at your own pace while still having access to available credit if another financial need arises. For many Canadians who are trying to regain control of their finances, this flexibility — combined with a lower APR — makes using a line of credit for credit card debt repayment a strategic and financially responsible decision.
Since you are aware of the distinctive aspects of credit cards and lines of credit, you should also know the pros and cons of each borrowing aspect to make an informed decision.
