I don't know if it's been posted yet, just tossing it out:
If you travel up with the windshield washer stuff the stores in most of the US, it'll freeze in the winter in Canada. I know this because the stuff they sell in the supermarkets in Albany that say "freezing point -20F" often freezes above that point. I'd suggest filling up with local stuff when you get up there. (My trick is to mix 1 bottle of isopro-HEET with 1 jug of the infamous "-20" stuff in the blue jug. That never freezes. If you go beyond that or use the methanol version of HEET you might take the paint off your truck.)
Don't forget to have fun!!
