While it is highly recommended to have some Canadian Dollars (CAD) for small purchases, public transit, or tips, Canada is a highly digital economy in 2026. Most vendors—from major retailers to small coffee shops—accept "Tap-to-Pay" via contactless credit cards, Apple Pay, and Google Pay. However, using USD in Canada is generally discouraged; while some border towns may accept it, they will often apply an unfavorable exchange rate and provide change in CAD. For the best value, use a credit card with no foreign transaction fees for the majority of your spending and withdraw a small amount of CAD from a local bank ATM upon arrival to cover "cash-only" scenarios like laundromats, some parking meters, or remote rural markets.
