Leg 01 · The river
Down the 401, past where the other brief ends
The first third is the country's most travelled freight road: the 401 along Lake Ontario to Kingston, then the seaway towns and Autoroute 20 onto the island. It is the exact corridor the Toronto–Montréal brief plots — and where that page finishes, this one is barely a third done. Past Montréal the A-20 keeps the St. Lawrence on its left through Trois-Rivières and Québec City, and the traffic thins with every hour east.
