After becoming cannabis-friendly on October 17, 2018, parks will become free sites for weed users. However, there are few restrictions like you cannot smoke in places where tobacco use is prohibited or in common campground areas. You can light up and smoke in the backcountry and on hiking trails.

Some provinces such as Ontario, Quebec, British Columbia, Nunavut, and Alberta will allow smoking on hiking trails as long as they do not lie within the campgrounds. Marijuana will also not be permitted in washrooms, parking areas, kitchen shelters, or within National Marine Conservation areas, historic waterways, and national historic sites.
