Well, Santa Fe is at 7,000 ft elevation in the foothills of the Rocky Mtns. so it gets cold here too. But, I'm willing to bet that Saskatchewan is colder most of the time.
From the reading I've done, any heat gain from your roof would (or should) be blocked by attic insulation. Solar heat gain can be a great thing, but the house must be designed for it in the first place. As I understand it, you want a cold roof surface to avoid ice dams driving water into the shingles and sheathing, with a well insulated attic to keep the house warm.
