From the Ontario MNR web site -
Ontario�s Crown land provides the opportunity for many outdoor recreational activities including camping.
Although most Crown land is available for the enjoyment of both Ontario residents and visitors, access to some Crown land may be restricted or limited. The Ministry of Natural Resources may post signs to limit certain kinds of travel or activity (including camping), as well as close forest access roads for reasons of public safety or environmental protection. Please contact the local MNR Office for more information about the Crown land in the area you hope to visit.
When camping on Crown land, all users are asked to undertake their activities in an ecologically sound and responsible manner, accepting the risks associated with their activities. Please remove all litter and enjoy and respect Ontario�s Crown land.
If you are interested in camping in an Ontario Provincial Park, please visit the Ontario Parks website for more information.
Residents of Canada
Residents of Canada may camp free of charge on Crown land for up to 21 days at any one site, except where posted otherwise.
Non-residents of Canada
If you are a non-resident of Canada, 18 years of age or older and wish to camp on Crown land north of the French and Mattawa rivers, a Crown Land Camping Permit is required, unless:
*You are a non-resident that is 18 years of age or older and are renting a camping unit (a camping unit can include a tent, trailer, tent-trailer, recreational vehicle or camperback) from a commercial outfitter in Ontario.
*You are a non-resident that is staying on a watercraft equipped for overnight accommodation, anchored on a Crown land water bed and not located within a regulated (green) zone or other signed prohibited area.
*You or your spouse owns property in Ontario - NOTE: access to regulated (green) zones remains prohibited.
Where Can You Get a Crown Land Camping Permit?
Non-resident Crown Land Camping Permits are available from numerous fishing and hunting license issuers and from Service Ontario centers in northern Ontario. The cost of a Non-resident Crown Land Camping Permit is approximately $10 per person per night. Members or persons in charge of a charitable or not-for profit organization may be eligible for exemptions to a Crown Land Camping Permit by applying in writing to the District Manager well in advance. Please contact the local MNR Office or call 1-800-667-1940 for more information on camping on Crown land.Downloadable Map of Green Zones, where no non-resident camping is permitted -
