Welcome to iRV2.
You would need a good 4 season coach , because no matter where you go in Canada , you can get winter conditions ; some years way worse than others. Vancouver , The Island , or the Southern Okanagan. All those area can get snow and extended times of freezing weather. Don't let the Chamber of Commerce tell you otherwise.
I'm sure you will find other members here in the forums doing the same thing, and get some first hand advice.
