www.enfieldmotorcycles.ca/find-a-dealer ...should find something out your way, I believe the new importer is in Calgary. I'll be at the Toronto Bike show on Saturday and R-E is slated to have a booth there. I'll let them know potential customers are having difficulty locating them and have very understandable service concerns.
I think the next bike show out your way is - January 20th-23rd TradeX Exhibition Centre, Abbotsford That might not be close to Okanagan, but shows are still the best place to find deals on helmets, gloves and accessories, plus you can do a lot of one stop shopping for a bike. Any dealer serious about representing their products usually attend the bike shows. You were asking about Triumph and Yamaha, both make fine motorcycles with modern Triumph engines actually being manufactured in Japan.
...hope this helps some.
