How long has he been cantering? Is it new to him? If so, he could be really enjoying it and waiting for you to give the cue to strike off again.. or getting impatient and going ahead and cantering without a cue. My horse did this, and a few other greenies I've seen do it too.
Halt halts and get your horse's mind re-focused.
