One problem with winter camping in Canada is that the evenings are dark so bring things to do indoors. Some provinces require winter tires and you don’t want to be buying them urgently to get out of a towing lockup. Alberta doesn’t require them and in BC you can get away with having chains on board. I take our C for a drive every month. In January I stopped on a small country road where I had to turn around using a driveway. Backing out of the driveway I couldn’t see very well due to bright sunlight and everything white - I backed into a snow drift and got stuck. I brought a shovel this month and didn’t need it. It’s the first warm day this February, only 4 below zero C. Twenty below expected again tomorrow.
We got our former rental MH in late fall and took our first camping trip in March to Jasper. Of course we got a big snowstorm on the way and stopped at a small campsite where we really enjoyed our MH despite a foot of snow and -10C. I just put a mitt over the freshwater drain tap and we had no problems with freezing. Now we know we can handle -10 but probably not much colder.
