That is a provincial regulation so varies. I looked after a fleet of light and medium duty trucks for a helicopter company, it drove me nuts trying trying to keep up with different regulations as they tried to out duel each other.
I don't need a special license to drive a moho but must have a special endorsement or class 1 cdl for a trailer over 10,000#. Air brakes also require an endorsement but I don't know if it is a different course than commercial which is not really relevant for our purposes. Check with your dmv for the final word.
