That's actually an interesting question. Habitat 67 looks to be directly south of Olympic Stadium.

Here are the coordinates for both:

Habitat 67: 45.500031,-73.543459
Olympic Stadium: 45.557378,-73.551968

So Habitat 67 is technically east of Olympic Stadium, although it is more south. Tell that to your average Montrealer, and their head will explode.
