Crown land is land owned by a monarch and usually public land which may be used by nomads and others for recreation and other purposes.
Canada
Crown lands in Canada:
Alberta
Public Land in Alberta breaks down in to 2 sub-categories – Public Land Use Zones and Recreational Public Land.
Ontario
In Ontario, Crown land covers 87% of the Province. It is most prominent in northern Ontario, and scarcer the south due to densely populated urban areas.[1]
Foreigners may camp on crown land other than green zones [2] by purchasing a Non-Resident Crown Land Camping Permit.
Lands "north of the French and Mattawa Rivers" require the permit[3]; it is not clear if the permit is required to the south.
Crown lands are free for Canadians to use at a given location for up to 21 days, except where posted, in a calendar year[4], after which they must relocate at least 100 meters. Failure to relocate can result in a fine up to $10,000.[5]
