I live in Wyoming, it gets in temperatures similar to yours at times, just this last weekend it was -19 and snowing and I was wearing my lost park parka with a t shirt underneath outside doing chores! I would highly recommend the Lost Park Parka. I have used it on a September elk hunt, ranching, and even cross country skiing and been warm every time! Worth every penny!
I think if you live in an area where there are a lot of colder temps it can be universal, I know it is for me- I use if for everything, even as a jacket to throw on and do chores outside as in Wyoming our winters are cold. I would think being from Canada you would need a warm thrown on as often as us here in Wyoming
