Why does the BMO card’s 5% lose to the 4% cards?
The cap. BMO CashBack World Elite pays 5% on groceries only up to $500 of spend per statement period — about $25/month, $300/year — then drops to 1%. A household spending $1,000/month on food earns more from an uncapped 4% (about $480/yr) than from BMO’s capped 5% plus 1% overflow (about $360). Headline rates without their caps are marketing; the worked table above prices the caps.
Cash back or points — which is worth more?
Cash is the honest default: a dollar is a dollar, with no redemption charts, transfer partners or seat availability deciding its value. Points cards can beat cash for people who fly often and redeem well (see best travel cards) — but for the typical household, and especially in retirement when travel patterns change, the certainty of cash usually wins. Our main table shows both kinds side by side.
What about the welcome offers?
They’re real first-year money — Momentum’s 15% intro (to $300, window closes Nov 1, 2026), CIBC’s up-to-$350, TD’s up-to-$350 — but they’re one-time. Choose the card on its steady-state math (the table above), then treat the offer as a bonus for choosing now. The hub tracks every offer’s end date.
Do these rates apply at any store?
Category coding decides — and the trap is Amex acceptance: several major Canadian grocers have historically not accepted American Express at all (Costco does). Before counting on SimplyCash Preferred’s 4%, confirm your actual stores take Amex. Visa/Mastercard category traps are smaller but real: warehouse clubs and superstores sometimes code as "merchandise," not groceries.
