I was snooping around the Government of Canada’s website the other day and stumbled upon the Atlas of Canada site. They have the full Atlas (Editions 1 through 5) available free for download. It’s very cool to look at what the country looked like in the early 1900’s. Some of the maps have disputed Canadian and American Borders, Explorer Routes, etc.
It’s worth a look if you’re into Canadian history or just like old maps.
Here’s the official Government of Canada’s Website if you want to look at all the Atlas of Canada Editions
