A few thoughts:
#1 - Don't mind the public building, but the residential buildings are somehow obstructive to me.
#2 - I think this one has grown on me. Might be my favourite.
#3 - lives and dies on how well the green roof works, and my guess is it won't given the harsh climate.
#4 - I don't mind, but think this is the most 'of its time' design.
#5 - Don't like the residential building on Banff Ave; it sterilizes half the block. The big shale roof somehow feels like it has the wrong slope to me somehow.
#6 - Has the best single idea; a rooftop terrace that would offer amazing views and pull visitors through the building. But not great otherwise. Also the video doesn't properly pronounce the name of the main geographical feature that inspired them, the "Bow" (as in bow to your overlord) river.
