I love my Leica, but I'm not expert on the history, and I could be wrong here, but I think the M6 is built in Germany. I think Canadian production ended with the M4 (or maybe M5) back in the early or mid-80's. I have a Canadian built M4-P which I've been very happy with. There are a number of web sites that'll give you Leica history just google Leica Cameras

Good luck with the repairs.
