I started Archery when I was living in Moose Jaw, bought a used bow off a friend and got some good advice from a local guy who was running an archery shop out of his rural property there.
Decide what your intentions are as far as what type of equipment turns your crank. Long bows and recurves are a lot different shooting than compound bows.
Get some decent advice and get properly fitted! Best to see a certified instructor, usually he will work in an archery shop, esp. if the shop also has shooting lanes.
Don't try to be a he-man and buy the baddest, fastest, heaviest poundage bow you can get. 45 (min poundage legal in BC, IIRC) pounds will put an arrow through a deer and most of the way through a moose or elk, usually. The faster bows shoot flatter, but they usually trade that off for magnifying any errors the shooter makes in technique. Better to get an easier shooting bow, work on technique, then if you feel the need, upgrade later.
Practice! Remember that when hunting, it's going to be that first shot that counts, not how well you shoot after warming up a while.
If you can, go walkabout out in the bush, stump shooting. Not necessarily stumps, but at about anything that you can pick out as a target. Buy some Judo Points for that. I have had terrible results with the copies, and will only buy the real originals. Found that the copies shedded the wire 'kickers' too easily. They work a treat on gophers and grouse too. But I have gone out and shot at golf balls, beer cans, dandelions, picked a tree branch, whatever. Estimate the range, and take the shot. It builds muscle, and muscle memory.
Rangefinding and practicing estimating ranges! If you have a rangefinder, use it, if you don't, make your best estimate, and practice until what you se matches where your arrow goes.
