Chemin du Roy was built between Montreal (Repentigny) and Quebec City from 1731 to 1737, for mail and as a means of travel for the key settlements in New France[REF]/Lower Canada.
The latter route, which became The Provincial Highway in 1917 (Ontario Highway 2 c. 1923), and the former which became a Dundas Highway in 1920 (Ontario Highway 5 in 1925), were the beginning of the provincial highway system in Ontario.
