Suffield CFB, Alberta, Canada

The claim: just north of Medicine Hat, less than 60 miles from the USA.

What it really is: Canadian Forces Base Suffield is the largest base for the Canadian military (after looking are the place via Google maps I can tell you that it is huge), and is used for defense development and research by the Canadian military, and as a training base for the British.

Not only is the base very vast, it also doesn't contain that many buildings, and none are large enough, or in large enough concentrations to even look like a prison camp.
