I have traveled this road several times. Seeing it is a "private" highway you have to pay the distance traveled. They take your license plate as you enter the highway per camera and they send you an invoice. Other charges apply such as tax and administration charges. This is a nice road to travel if you don't mind paying the toll fee. You can also take the 401 if you don't mind the traffic. Of course its free. Stay away from this highway during rushhour.
Hope this helps. Cheers Gerald
