I sweat terrible hiking in the Impertech stuff, although it works for many people. I've not been to Canada, but my First Lite SEAK jacket and Kuiu Yukon pants have worked well on 3 trips to Alaska.
Any breathable rain gear will wet out eventually I think, even the best stuff. For that reason I always take a decent ultralight poncho too. If I get in a downpour that I'm not hunting in, just waiting it out, I can throw that on. Mytrailco made my old one, and my new one is from Wilderness Innovations. I have a Onetigris one too that's cheaper and seems to work fine. They can be multipurpose too, I've made a windbreak or glassing shelter from mine a few times different places.
We have hunted in pairs in AK and each pair of us carries a Seek Outside DST tarp too. It's a good 10x10 tarp we can glass under in bad weather. One guy carries the spotter and tripod (usually me since I also have the poncho) and the other carries the tarp and stove. We were hunting from a drop camp, not backpacking.
