Response Yes you can have cathedral ceilings in Canada -- but the trick is to make them thick enough to have lots of insulation and lots of ventilation both.
The graphics show three different ways to accomplish that. And of course always pay attention to the critical detail of good air sealing at the ceiling level to keep hot air out of the roof space.
