I have hauled hay, sun up to sundown under bright and sunny skies in 100+F temps wearing a loose t-shirt and jeans. Some of the other guys were shirtless and one tough dude would wear cutoffs. Youth and continuous expose to heat helped a lot (none of us had AC in our lives at the time).
The heat was not the problem for us that cold weather was. To put on enough to stay warm, I would have to pad up like the little brother in “Christmas Story.” And what happens when you get wet? How can you pull a calf in all those layers?
The limited time I spent in the ice and snow convinced me I wanted no more of it.
Since I am not a resident of the great white north, how do have manual dexterity in gloves or mittens thick enough to stay warm? How many sizes larger than your feet do your shoes have to be to have enough socks on to keep your toes from freezing? Does your construction (like home building and roofing) work stop in winter?
Not knocking you folks that live in the freezer - I wish more folks felt like you and quit moving here. I do know I might make a short visit (would like to see the northern lights), but I could never live there.
