I love Vancouver, but there's some unforgivables in here. I'm presenting these in then and now format, hope that's ok, it's quicker for me than tracking down just the old photo plus there's some reference to what replaced the old buildings.
Birks Building, probably the biggest architectural loss in this city:

This could also be considered the city's greatest loss, the 2nd Hotel Vancouver:

Some notable theaters:
