No family member or friend willing to take on the task? Any older person you could drive to the store for practice? I didn't have to parallel park for my driving test, though everyone else I know did, and I practiced. Okay, here is the theory I was told:

Pull up along next to the car in FRONT of the space you are trying to pull in to. Then put it in reverse, and when you are halfway down the length of that forward car, cut the wheel so you are backing into the space. When you are halfway in, start straightening out the wheel. You may have to adjust a little once you are in the space, but one pull forward, then backwards into the perfect position ought to do it! Slowly, slowly, practice makes perfect.

Okay, now my caviat - I have SEEN it done, honest I have. Many times. I do it backwards from that, and pull into the space, then usually adjust a couple times, but I also look for two open spaces so I can just pull smoothly in! (I never had to parallel park before sophomore year of college. Everywhere in my hometown had parking lots or driveways!)

I know nothing about insurance rates in Canada - could you call around to other companies for a better rate?
