Is there a good R2R Tape technician in Calgary?

I have a Pioneer RT-909 R2R that is in very, very good condition, but has never been professionally looked at or serviced. It plays well and I have no qualms about it's performance, but I'm thinking it would be a good idea to have it looked at. I'm confident with a little professional help it could last for many more years, which is what I'd like.

I have the original shipping carton, but it's somewhat tattered, so shipping it out is not an option at the moment. Hence my quest in trying to find a local tech.

Any info is most appreciated. Thanks!
