Locally, SCCBC is the body that will issue your road racing licence. Every year they have at least 1 driver training clinic where you take the training, and at the end of the day if you pass the training program, you'll be given a novice licence. I am not entirely certain of the details because I am not a road racer (yet?), but you should head over to the
SCCBC website and fire off some emails to contact them.
As good as VCMC and UBCSCC are, they are more focused on autox, and to a lesser degree, lapping days.
Even at the amateur level, it's a very big world out there for motorsports. From autox to lapping days, to solo sprint, to road racing (and vintage racing), to hill climb, to ice racing, etc. There are lots and lots of different options for you to explore. Among other things and in addition to your intended type of motorsports activity, you'd really want to consider all the costs and logistical support that is required. (Truck + trailer are probably minimum requirements since very few race cars are still road legal. Besides, do you really want to run your race car and its race suspension and alignment on the street?) Additionally, in case you haven't realized, road racing gets a little expensive. Cheaper alternatives such as chump car and maybe "just" lapping days should also be considered.
As far as tracks are concerned, I'd say we are already very much blessed with some great tracks in the PNW. Mission is smaller, but it is close and has all the basic elements that you'd see in other places (except for elevation changes). Pacific Raceway is only 3 hrs away, and the Ridge is only 4. Both are beautiful and tremendously fun tracks to drive. Portland International Raceway is only 5 hrs away, and a tad further to the east, Oregon Race Park is ~6.5 hrs from Vancouver. None of those are all that far away.
