Because technically there are places in Canada where -35 doesn't cut it, my area does get below -35 (before windchill is factored in) many times per year.

Yeah it’s only tested at -35C, so it could possibly crank lower. The only thing you’re sure about is if an oil is 5W it’s not going to be good under -30 C or it would have been labeled 0W. I’m going to also assume the test has some margin and the oil also.
