TORONTO - With the busy summer travel season set to take flight, Air Canada is about to begin clamping down on carry-on baggage to ensure it meets regulations.

Starting next Monday at Toronto's Pearson International Airport, airline staff will be stationed at both check-in and security checkpoints to ensure carry-on bags meet size and weight requirements.

Bags that meet the airline's carry-on dimensions will receive a red tag, which the airline says will help reduce wait times at security and "help avoid flight delays caused by larger bags being checked at the gate."

Air Canada (TSX:AC.B) says carry-on bags which exceed the regulations will need to be checked and "standard fees will apply."

The airline says if passengers get to security and need to check a bag that exceeds size limits, they will receive a special card to get quickly back to a check-in agent, and then on to the departure gate.

Transport Canada rules allow passengers to carry on two unchecked items.
