Vancouver isn't really a canyon city. The CBD is so compact, and we all know about the point tower form. You need long streets which are lined with closely-spaced, tall, fat buildings with uniformly-small setbacks. Which is pretty well the exact opposite of the direction Vancouver has gone.

The only streets that come to mind that would most closely resemble canyons would be Cordova west and parts of Alberni. These streets are not very wide and the buildings' placement, height and spacing emulate a canyon, even though it isn't. It has that presence when walking those streets.
