Most Canadians use one credit card for everything. Points experts use two or three — each optimized for a specific spending category. This is called a "card stack" and it's how you go from earning 1x points on every dollar to earning 3x–5x where it matters most.
Why One Card Is Never Enough
No single card offers the best earn rate across every category. The Amex Cobalt is unbeatable at 5x on groceries and dining — but earns only 1x on gas. A WestJet card might be excellent for Air Canada bookings but ordinary everywhere else. The solution is simple: use the right card for the right purchase.
The Concept of Multipliers
A multiplier is the bonus earn rate a card offers in a specific category. If a card earns 5x on groceries, you're earning 5 points for every dollar spent — versus 1 point on a basic card. On $1,500/month in groceries, that's the difference between 1,500 and 7,500 points per month. Over a year: 18,000 vs. 90,000 points. That gap is the difference between a short-haul economy redemption and a business class flight to Europe.
A Starter Card Stack for Canadians
| Card | Use It For | Earn Rate | Why |
|---|---|---|---|
| Amex Cobalt | Groceries, restaurants, food delivery | 5x MR pts | Best food multiplier in Canada. MR transfers to Aeroplan 1:1. |
| RBC ION Visa | Groceries, drugstores, streaming, subscriptions | 3x Avion pts | Visa acceptance means it works everywhere Amex doesn't. Great Cobalt backup or standalone for Visa-only stores. |
| Scotia Passport Visa Infinite | International purchases, anything Amex not accepted | 3x Scene+ (grocery), 0% FX | No foreign transaction fees saves 2.5% on every international purchase. |
| TD Aeroplan Infinite | Gas stations, Air Canada bookings | 1.5x Aeroplan | Direct Aeroplan earn + free checked bags on Air Canada. |
A Premium Card Stack
Once you're comfortable with the basics and flying business class, a more advanced stack might look like:
- Amex Business Platinum — for all business expenses (1.25x MR, 120K welcome bonus, Centurion Lounge)
- RBC Avion Infinite Privilege — travel purchases (2x Avion, lounge access, insurance)
- RBC Avion Business Infinite — remaining business expenses (1.25x Avion, $199 fee is exceptional value)
Managing Multiple Cards Without Chaos
The main concern most people have about multiple cards is complexity — missing payments, losing track. The solution is simple:
- Set all cards to autopay the full statement balance every month. No exceptions.
- Use a notes app or simple spreadsheet to track: card name, annual fee date, points balance, welcome bonus status.
- Review each card once a month when the statement arrives — 5 minutes is enough.
The daily management is not complicated once the system is set up. Most experienced points collectors spend 15–30 minutes per month maintaining their stack.
Credit Score Considerations
A common concern is that multiple credit cards will hurt your credit score. In practice, the impact is minimal if you pay on time and in full. What matters most to your credit score is payment history and credit utilization — both of which you control. People who've been in the points game for years often have excellent credit scores precisely because they're disciplined about paying balances in full.
