Canon made quite a few rangefinder cameras in the early days. At present I only own one rangefinder camera, that being the Canon IIS2. I previously owned the Canon III, and consider both of these to be fine cameras.
Here's a list of those early Canon rangefinder cameras.
Many of these can be found on eBay in excellent condition, and at a reasonable price.
I have a IIb, it's like having a Barnack Leica with a better viewfinder - one window and three(!) magnifications. Lovely little cameras, alas mine is in such nice condition I wouldn't use it for day-to-day walking around with. The build quality of these cameras is superb.
