Yes, plus while every Canadian home has heating, not all homes have air conditioning. Optimizing the roof for the summer makes a lot of sense.

We had a steep roof in the Okanagan which rose about 20ft to the peak. That extra room was problematic in winter for heating but a life saver in the hot, sunny summer. The loft was unbearable during the summer.

A neighbor with a low roof would run a sprinkler on his roof all summer long, that's how bad the heat would get.
