Yes, Canada has free camping options, often referred to as "Crown land" or "public land" camping. Approximately 89% of Canada's land is owned by the government and is open for public use, including free camping. These campsites are typically primitive and dispersed, with no facilities or amenities. It's essential to come prepared and practice Leave No Trace principles to preserve the natural environment.
In Manitoba, around Winnipeg, you can find free camping on provincial Crown land. However, you should check the specific regulations and restrictions for the area you plan to visit, as some areas may require permits or have other limitations.
