Just got back from a full AC LHR -> YYZ flight. All the bags with Priority tags came out dead last -- it was weird seeing all the business class cabin pax waiting around as the pax with non-tagged dwindled away...

It took 1.5 hours from arrival at the gate to get to the taxi rank

Unrelated point, but immigration was log-jammed with about 4 747 flights including one originating from India -- so there was a long wait. Staff there directed some folks with children to the crew line as the kids were getting cranky with the delay. My AC crew arrived and one of the FAs loudly proclaimed as she was pushing to the front of the line "This is line is for CREW ONLY" -- an ugly scene for a while as some pax explained that they had been told to go there.

I expect this has been discussed before but is there any reason why Canadian immigration does not have lines for Canadian residents like virtually every other country?
