Ooh, mapping was a good idea.
I found more than I realized we had. There are a few that I skipped - that's because, despite appearances, they're actually the visible top floor of a parkade, not a surface lot:
I also excluded one that's becoming a Marriott Hotel.
EDIT: Aww, my picture got cut off. And right above a big one (Delta Hotel parking lot) as well. Just know there's one more big one at the bottom left.
