The Short Answer
Most accelerated earn rates in Canada stop at a spending threshold. Spend past it and the card quietly drops to its base rate for the rest of the period.
Of the 122 cards in our catalogue, 63 disclose some form of earning cap and 59 publish none. The caps that matter are the ones on a card's headline category — the 5% or the 5x that sold you the card in the first place — and they range from $1,000 a month to $50,000 a year.
What an Earn Rate Cap Is
A cap is a spending ceiling on an accelerated category. Below it you earn the advertised rate. Any money you spend beyond the threshold earns rewards at the base rate — 1% or 1 point per dollar in most cases — until the threshold resets.
The advertised rate is what gets put in front of the public to sell a card, but the real deciding factor is the earn cap. Two cards can advertise the same 5% on groceries and pay out completely differently, depending on whether that rate stops at $1,000 a month or carries on to $30,000 a year.
Caps come in two shapes, and the difference matters more than most people expect:
- Annual caps reset once a year. This gives you more flexibility, as any spending cap you don't use one month carries forward to the next, so you can have a few quiet months and still use up the cap in one heavy one.
- Monthly caps reset every month. Unused room does not carry forward, so there is constant pressure to use the full cap each month or lose those rewards for good.
The Caps Worth Knowing About
Verified against our catalogue on 5 October 2026. The caps listed below are ongoing earn caps, not welcome offer limits. Those are a separate entity, and we left them out of the table because they change constantly, usually every 3 to 6 months.
| Card | Annual fee | Capped category | Cap | After the cap |
|---|---|---|---|---|
| National Bank Platinum Mastercard | $70 | Accelerated earn | $1,000/month | 2 pts → 1.5 pts per $1 |
| National Bank World Mastercard | $115 | Groceries, restaurants | $2,000/month | Tiered rate reduction |
| National Bank World Elite Mastercard | $150 | Groceries, restaurants | $2,500/month | 5 pts → 2 pts per $1 |
| TD Rewards Visa | $0 | Groceries, dining, transit | $5,000/year | Base rate |
| ATB Gold My Rewards Mastercard | $0 | Accelerated categories | $10,000/year | 1.5 pts per $1 |
| Triangle Mastercard | $0 | Groceries (1.5% CT Money) | $12,000/year | Base rate |
| Triangle World Elite Mastercard | $0 | Groceries (3% CT Money) | $12,000/year | 1% |
| TD Platinum Travel Visa | $89 | Groceries, dining, transit | $15,000/year | Base rate |
| National Bank ECHO Cashback Mastercard | $30 | Gas, grocery, online | $25,000/year | 1.5% → 1% |
| TD First Class Travel Visa Infinite | $139 | Groceries, dining, transit | $25,000/year | Base rate |
| Amex Cobalt | $191.88 | Eats and drinks | $30,000/year | Base rate |
| ATB World Elite Mastercard | $120 | Accelerated categories | $50,000/year | 2 pts per $1 |
Two patterns stand out. National Bank is the only issuer here using monthly caps, and its ceilings are the lowest in the table. The second thing is that the Triangle grocery bonus does not apply to Costco or Walmart purchases at all. That is a big exclusion, considering that these cards market themselves as grocery rewards cards.
Monthly Caps Bite Harder Than Annual Ones
The National Bank World Elite caps accelerated grocery and restaurant earning at $2,500 a month. Annualised that is $30,000 — identical to the Amex Cobalt's $30,000 a year on eats and drinks. The two are not equivalent. The example below shows how earning differs between the two.
Take a household spending $1,200 a month on groceries. Under either cap, nothing happens. They never come close, and the advertised rate is the real rate.
Now take a household spending $3,000 a month:
- Against the $2,500 monthly cap: $500 a month falls to the base rate. Over a year that is $6,000 of spending earning 2 points per dollar instead of 5 — a shortfall of 18,000 points.
- Against a $30,000 annual cap: the same $36,000 of annual spending overshoots by $6,000 too. Identical outcome.
The loss of rewards is the same as long as the monthly expenditure is fixed month after month. The real difference is seen when the spending varies from month to month. Let's assume a household is averaging $2,400 a month but spends $4,000 in December and $1,500 in January:
- The annual cap sees $28,800 of spending against a $30,000 ceiling. Nothing is lost.
- The monthly cap sees December blow past $2,500 by $1,500, while January's unused $1,000 of headroom simply evaporates. That $1,500 earns the base rate for no reason other than timing.
A monthly cap is therefore strictly worse than its annualised equivalent. It is never better, and it is worse exactly when your spending is lumpy — holidays, back-to-school, a big shop before guests arrive.
The Cards That Don't Cap at All
Fifty-nine cards in our catalogue publish no earning caps. Among the more competitive:
| Card | Annual fee |
|---|---|
| BMO Ascend World Elite Mastercard | $150 |
| Neo World Elite Mastercard | $149 |
| CIBC Aventura Visa Infinite | $139 |
| RBC WestJet World Elite Mastercard | $139 |
| Brim World Elite Mastercard | $89 |
| RBC ION+ Visa | $48 |
One caution that matters more than the list itself: "no published cap" is not the same as "no cap." What our data records is that the issuer does not disclose one. Program terms can still include limits on promotional multipliers, partner offers and bonus events, and those terms change without a press release. For a high spender planning around an uncapped category, the cardholder agreement is the source of truth, not a comparison table — ours included.
How to Tell Whether a Cap Will Affect You
Three questions, in order:
- What do you actually spend in that category each month? Not your estimate — use your last three statements as an anchor to get the exact number you spent on each category.
- Is the cap monthly or annual? If monthly, check your worst month, not your average. That is the one that gets clipped, and it should be the decision maker.
- What is the drop? Falling from 5 points to 2 is a 60% cut on the overspend. Falling from 1.5% to 1% is a third. The size of the step determines whether the cap is an annoyance or a dealbreaker.
If your category spending sits below the cap, the cap is irrelevant and you should pick on the headline rate. If you are above it, the honest comparison is your blended rate — accelerated up to the ceiling, base above it — which is the number the rewards calculator works out from your real spending.
When a Capped Card Still Wins
A cap is not automatically a reason to walk away.
The Amex Cobalt caps eats and drinks at $30,000 a year. Reaching that means spending $2,500 a month on food, which is next to impossible for the majority of cardholders. For everyone else the cap is a line in a document they will never touch, and the card competes purely on its earn rate.
The National Bank ECHO caps gas, grocery and online purchases at $25,000 a year against a $30 annual fee. Hitting it requires over $2,000 a month in those categories — possible for a family, but if you get there you have already earned well past the fee.
A low cap on a card you were going to use lightly costs you nothing. But even a high cap can limit your rewards if you plan to put all your spending on that one card. The question is never whether a cap exists, it is whether your spending reaches it — which is why a cap should change which card you pick, not whether you pick a rewards card at all.
