Note: This guide covers RV and trailer camping in cold weather. Winter tent camping and backcountry camping in Canada are a different discipline with different gear requirements — sleeping bag ratings, shelter systems, layering, and avalanche awareness for mountain terrain. If that's what you're planning, this guide is not the right starting point.

The consequences of getting this wrong: frozen tanks at 3 AM, burst water lines, and a very expensive repair call. Freeze damage is commonly excluded from RV warranties — check yours.
Rental RVs are almost universally 3-season. If you're renting and planning to camp in October or later anywhere outside coastal BC, ask the rental company directly about their cold-weather rating.
The South Shore and Annapolis Valley stay mild enough for camping through November without significant cold-weather preparation on a 3-season rig. Some private parks in the Yarmouth and Lunenburg areas operate year-round. Cape Breton Highlands campgrounds run mid-May to late October. If you're going in December or later, pack accordingly and verify specific park status before driving four hours only to find the gates locked.
Carbon monoxide — read this before you run any heat
CO has no smell, no colour and no taste. In winter you are running combustion appliances harder inside a small, sealed space, which is exactly the condition that kills people.
Some Northern Stay campgrounds offer winter or year-round access — check each park's season on its listing.
