Flight delay due to staff shortage. No snack or drinks served. Toilets had water collecting on the floor.

Flight was delayed due to crew/co-pilot change over delay and Pearson scheduling issue. Flight didn't leave until 20:05 which was 15 minutes before it was supposed to land in YYZ.

Not great. Missed my connection flight, due to AC issue. We were sitting on the tarmac for 90 mins before taking off.

Air Canada was fine but air Canada rouge and air Canada express was terrible with luggage delays. First flight was cancelled so my luggage did not make it to my destination with me. The second flight returning not sure why but my luggage did not make it on my connecting flight. Overall terrible with handling luggage.

Comfortable seats with good leg room. But not screens on seat backs.

Air traffic delay meant boarding started, then plane was evacuated and passengers sent back to the terminal for 1 hour. Very little information shared.

Too many delays. Seats too small. A budget airline. Will never fly Air Canada again.

Horrible, we were on a little DeHaviland 400 that was really small and shaky. I am 5' 4" and I had to duck my head to get in it felt like an old war plane.

It might have been closer to being on time. Maybe next time I could fly from London to Toronto?

Air Canada canceled my flight last minute and I gave me next’s day night time my flight. No accommodations at all. I have a function on Xmas eve. So I had to took rental car last minute.i never ever book a ticket with Canadian airlines at all.
