Boondocking, or camping without facilities and hookups, is legal in Canada but only in certain areas. Crown land, which makes up about 41% of Canada's landmass, is available for boondocking, but this varies by province. In some provinces, like Ontario and British Columbia, you can camp for free on Crown land for up to 21 days. However, in other provinces, like Québec and New Brunswick, camping on Crown land is more restricted.
It is essential to research and follow local regulations and guidelines for boondocking in the specific area you are interested in. Stay within designated camping areas, and always practice Leave No Trace principles to minimize your impact on the environment. You can also find private boondocking spots on Hipcamp.
