We had originally booked our flight from Punta Cana to London Ontario but our flight from Toronto to London was rescheduled and we would of had a 14 hour layover in Toronto before caughting our flight to London which is unacceptable. So we canceled our flight to London with no compensation and booked Robert Q Airbus from Toronto to London. We are not planning on using Air Canada for any more travel trips. In the last year and a half, Air Canada has rescheduled my flight from Toronto to London 3 times and forced me to cancel the flight and take Robert Q to London to avoid a long layover in Toronto. I received no compensation for the flight which is unacceptable. I'm very disappointed in the way Air Canada always rescheduled my flight from Toronto to London.

Terrible…. Reported missing luggage’s with injectable meds that needed refrigeration. Yet, delivery could not be expedited. Luggage’s were delivered 5 days after arrival. The meds were useless as ice pack had melted. So disappointed!!!

Terrible… Luggage’s missing for 5-days. Not expedited despite notifying them that insulin and ozempic were in bags and required refrigeration. I’m extremely disappointed. Meds were useless upon delivery as ice pack had dissolved and meds were warm and not useable because their efficacy and potency are now questionable . I’m so disappointed and expecting a full refund for the checked in bags.
