Air Canada is generally very strict with its 50 lb (23 kg) weight limit for standard checked bags, especially on domestic and trans-border routes. In 2026, the airline uses highly calibrated digital scales at both full-service counters and self-service bag drops. If a bag exceeds the 50 lb limit by even a small amount, the system will typically flag it, requiring the passenger to either remove items or pay an overweight fee, which usually starts at $100.00 per bag. However, for those traveling in Business Class, Premium Economy, or holding high-tier Aeroplan Elite status, the limit is often increased to 70 lb (32 kg) per bag. To avoid these steep penalties, travelers are advised to use a portable luggage scale before arriving at the airport. It is also worth noting that bags exceeding 70 lb (32 kg) will not be accepted at all for safety reasons related to the health of the ground handling staff and baggage handlers.
