Anything in Montreal?
Another vote for Camtech in Hamilton. Good work and good prices (a rare combination.)
I've had the following work done by them:
Rollei 2.8F Planar - CLA with shutter timing
YashicaMat LM - CLA with shutter timing
Pentax MZ-S - troubleshoot and repair faulty shutter speed dial
Each job only took about a week. Great guys at the store too, a pleasure to deal with.
My other camera is a Pentax
