The Montreal and City of Ottawa Junction Railway (M&OJ) would run south-east from Ottawa to Coteau, QC, just west of Montreal. The line would connect to the Grand Trunk Railway (GTR) at what became known as Coteau Junction, also known as Coteau Station. Crossing the GTR main line, the Coteau and Province Line Railway and Bridge Company (C&PL) ran southeast, bridging the Soulanges Canal and then the St. Lawrence River to Valleyfield, QC, thence across southwestern Quebec to Cantic, QC and then crossing the northern end of Lake Champlain between Alburgh, VT and Swanton, VT where it ended at a connection with the Central Vermont Railway (CVR).
