Basically once you are far enough north you are most likely on crown land once your far enough from any major cities. Your best bet for a proper camping trip would be to pick an area you like, with a small town nearby.
>My personal favourite area for camping, many rivers and waterways offer great canoeing and fishing. Wildlife is abundant. https://en.wikipedia.org/wiki/Temagami>To find out what exactly counts as crown land you can check the official website of whatever province you intend to visit and it should have something similar to whats on Ontario's. https://www.ontario.ca/page/crown-land-use-policy-atlas
