You're in Calgary. Cheap and good lessons abound. Every fly shop puts on lessons that not only cover casting and allows you to try different rods, but covers rod and equipment selection, knots, what parts of a stream or river hold fish, etc. Heck, the shop on 1st. street downtown charges you around $200 and something for the day and GIVES you a rod and reel combo with line.
Or you can try to learn on your own and catch a fish in 2015 like Guitarplayingfish.
