Nope, always inside seatbone to ask for canter! If you sit outside, it unbalances the horse, and gives a higher chance for counter canter, or with a green horse, no canter.
Inside legs give the impulsion, outside leg keeps the horse in place.
Raising your inside hand slightly will also help with the bend.
If it is untrained under saddle, please say and I can help develop further, apart from that, mildot has summed it up.
I don't know what style you ride, but my inside leg is ALWAYS my cue for canter, my outside leg acts as my straightning/bending rod in case I want to do canter half pass- my outside leg is already asking for canter, so how do I ask for half pass? Always inside leg ;)
