can she trot? or does she pace?
have you ever worked her over cavaletti? Cavaletti are hard to do while pacing, so encourage a trot. I am not sure if this is a fact, but one person I knew used cavaletti to help the horse break up the two sides of the body and then would ask for canter.
Pacing uses the body in lateral halves, while troting in diagonal halves. in the canter, the horse starts with one back foot, then has two diagonal legs form a kind of "fence" and then the horse continues "over" the fence with the front leading foot. That diagonal pairing is really important.
