Dressage is a progression from the easiest to the hardest. This not only includes various movements but the location of where a movement is asked for.
In the beginning the canter is asked for going into the first corner of the short side or end. The reason is that it is simply easier and the horse is less likely to run. Later on the horse is asked to canter at the start of the long straight side. For a canter to be correct true and balanced from this location it requires more training and balance.
The point above is you should be attempting your canter from a bend ...either going into a corner or on a large circle.
