An Alternative Vote system does not solve the major issues of First-Past-The-Post, and can still have wildly distorted outcomes relative to vote preferences. Unless combined with multi-member districts (aka Single Transferable Vote) it's barely/not an improvement for Canada -- it's a convenient option for the largest parties because it rarely makes a difference to the outcome and the votes all trickle back to them anyway, so they can make a change without making a change.
