The Canadian Subdivision is a railway line in the state of New York. It runs north–south along the west side of Lake Champlain from the vicinity of Schenectady, New York, to Rouses Point, New York, on the border with Quebec. While the oldest part of the line was built in 1832–1833, the majority was constructed between 1869 and 1876. Once part of the Delaware and Hudson Railway main line, today Canadian Pacific Kansas City owns the line. Amtrak's Adirondack operates over the full length, providing daily service between New York City and Montreal.
