Most Canadians carry 2 credit cards — here’s how to know if you’re helping your credit score or hurting your wallet

Most Canadians wonder at some point: “How many credit cards should I have?” The answer isn’t one-size-fits-all. It depends on your spending habits, financial goals, and how disciplined you are when using credit.

In Canada, nearly 9 in 10 adults have at least one credit card, and the average Canadian holds between 2 and 2.5 cards. For some, one card is enough. For others, carrying two or three credit cards offers better flexibility, stronger rewards, and the ability to sustain a healthier credit score.

Why having more than one credit card can be a good thing

It can be tempting to apply for multiple credit cards when new credit card offers pop up. But the underlying reason for applying for a new credit card should be grounded in other reasons. Here are some common reasons why having multiple credit cards is a good idea.

Improve your credit score

One of the most important factors in your credit score is your credit utilization ratio — how much of your available credit you use. By spreading your overall spending across multiple cards, you can keep this ratio low, which helps your score.

A healthy Canadian credit score falls between 660 and 724 (considered "good"), with credit scores between 725 and 759 considered "very good" and scores above 760 considered "excellent."

The key with multiple credit cards is to always pay your bills on time, since payment history makes up 35% of your credit score. Aim to do this for multiple credit cards and you can establish a strong, healthy credit score relatively quickly.

Take advantage of sign up bonuses

Canadian credit card issuers frequently offer welcome bonuses worth $250 or more. Premium travel cards can offer thousands of dollars in value through loyalty points and perks. Many Canadians carry multiple cards to cycle through these offers — taking advantage of loyalty bonuses and travel perks.

Maximize your rewards

No single card offers the best rewards across all spending categories. That’s why Canadians often pair cards to boost earnings:

• Amex Cobalt: 5x points on food and dining
• Scotiabank Momentum Visa Infinite: 4% cash back on recurring bills, 2% on transit
• Tangerine Money-Back Mastercard: 2% cash back in up to three chosen categories
• RBC British Airways Visa Infinite: Free annual companion flight

With two or three cards, you can earn higher rewards on groceries, travel, gas, and streaming services without overspending and even cut your travel costs significantly in the process.

Benefits tailored to your lifestyle

Some cards include unique perks that replace services you’d otherwise pay for:

• Triangle World Elite Mastercard: free roadside assistance (worth ~$100 annually)
• Wealthsimple Cash Card: no foreign transaction fees (saves 2.5% to 3.5% on overseas purchases)
• PC Financial Mastercard: earn PC Optimum points to redeem for groceries

How many credit cards are too many?

Technically, there’s no upper limit — as long as you can manage each credit card responsibly. But when increasing the number of credit cards in your wallet be sure to understand that each credit application will results in a hard inquiry — a credit score hit that temporarily lowers your credit score by 5 to 10 points. To avoid having these credit score hits hurting other aspects of your life, be sure to only apply for credit cards when other financial milestones are not being processed. For instance, avoid applying for new credit cards if you plan to apply for or renew a mortgage, get a car loan or considering another type of loan.

In general, follow these guidelines:

• Aim for at least two cards: one primary and one backup (ideally from different networks like Visa and Mastercard).
• Stick with one card if you’re new to credit or worried about overspending.
• Space new applications by at least six months to avoid damaging your score

When you should only have one credit card

Although having multiple credit cards clearly has its advantages, there’s nothing wrong with having a single credit card. That said, if you’re going to carry only one credit card, you’ll want to make sure it’s the right one.

Ideally, you want to choose a credit card that lines up with your spending or goals. So pick between travel rewards or cash back. You’ll then want to determine if you’re going to pay an annual fee or not. Generally speaking, credit cards with an annual fee come with better benefits.

Anyone who’s worried about controlling their spending should also only have one credit account open. Even if you’re not charging much or anything at all to your card, you’ll still be able to build your credit score. If keeping the credit card could still tempt you to spend, just put it in a box at home so it’s out of sight and out of mind.

Potential pitfalls of too many credit cards

There are strong reasons to limit your credit access to just one credit card:

• Complexity: Multiple billing cycles and due dates can be tough to track.
• Overspending: Chasing rewards isn’t worth it if you carry a balance.
• Impact on big purchases: Too many recent applications can weaken your credit profile before applying for a mortgage or loan.

To help minimize drawbacks, be sure to set up automatic payments or align billing cycles to avoid missing payments.

How often should you apply for a credit card?

While having multiple credit cards can help you improve your credit score, this doesn’t mean you should get carried away by applying for multiple credit cards every few months. This could also impact your credit score negatively due to multiple hard inquiries.

We recommend you space out credit card applications by at least six months to lessen the impact of multiple credit checks. The good news is that the impact on your credit score is fairly small (five to 10 points for each hard inquiry), and the impact doesn't stick around for long. You can easily offset the credit score ding by making your payments on time.

You should also not apply for new credit cards if you plan on making a major purchase in the near future. For example, if you’re considering applying for a mortgage or a car loan, you will want to ensure that your credit score is as pristine as possible. You don’t want to feel the impact of too many credit card applications hurting your credit score when you need your credit to be at its best.

This is why we suggest only applying for a new credit card when it makes sense for your financial situation. It will sometimes require you to turn down that generous offer, no matter how tempting it is.

How having multiple credit cards impacts your credit score

Having multiple credit cards is likely an easy way to build up your credit score. Your score is a number that falls between 300 to 900. If your credit score is between 660 and 724, your score is considered good. A score between 725 and 759 is very good, while 760 or higher is considered excellent.

It doesn’t matter if your credit score is good, very good, or excellent, you likely won’t have a problem securing additional credit. However, someone with a credit score of around 660 may have a harder time getting approved for more credit cards than someone with a score of 800.

You might think that this implies that people with excellent credit scores have quite a few credit cards, but there are many other things that affect your credit score. That includes how much you owe, the length of your credit history, the types of credit you use, and even how often you apply for credit.

Here’s the exact breakdown of your credit score:

• Payment history: 35%
• Outstanding debt/credit utilization ratio: 30%
• Length of credit history: 15%
• Public records: 10%
• Credit inquiries: 10%

Making your payments on time is the most important factor regarding your credit score. Your payment history is another significant value of your credit score, so if you intend on having multiple credit cards, it’s essential that you keep track of your payment cycles so that you always make your payments on time.

Your credit utilization is a significant portion of your credit score because it reflects how much money you owe compared to how much credit you have access to. Opening a new credit card and having multiple credit cards can help with this number because you’re hopefully increasing your overall credit limit without increasing your debt levels.

Your length of credit history is also vital because lenders want to see that you have a stable credit history. This doesn’t mean you should never close a credit card down, but you should think twice before switching credit cards. While applying for new credit cards will help you boost your credit utilization ratio, it’s difficult to beat the importance of building a payment history.

Credit inquiries account for 10% of your credit score. Remember, spacing out your credit card applications is crucial. Don’t hurt your credit score.

Bottom line

For Canadians, the “right” number of credit cards is usually between two and three. That’s enough to:

• Keep a strong credit utilization ratio
• Earn rewards across multiple categories
• Maintain a backup in case one card isn’t accepted

But if you’re struggling with budgeting or just starting out, one carefully chosen card is all you need.

Rule of thumb: More cards can work in your favour — but only if you’re financially disciplined. Otherwise, simplicity wins.
