When visiting Canada in 2026, it is overwhelmingly better to use a card for almost every transaction. Canada is one of the most "cashless" societies in the world, and nearly every merchant—from high-end boutiques in Toronto to small coffee shops in the Rockies—accepts contactless "tap-to-pay" via credit card, debit card, or mobile wallets like Apple Pay. Most travelers find that a no-foreign-transaction-fee credit card offers the best exchange rate and highest security. However, it is still wise to carry a small amount of "loonies" and "toonies" (Canadian $1 and $2 coins) or $5 bills for specific situations: some very small "mom and pop" diners in rural areas, certain farmers' markets, or coin-operated laundry machines. Also, if you plan to visit remote indigenous communities or far-northern territories, cash becomes more necessary as satellite-linked card terminals can be unreliable. For the average 2026 tourist, a card is the primary tool, with about $50 to $100 in physical Canadian dollars as a "just-in-case" backup for the entire trip.
