The Maple Leaf was a passenger train pool operated by the Canadian National and the Grand Trunk Western Railroad ("Grand Trunk") between Chicago, Illinois and Toronto, Ontario. It operated from 1927 to 1971. The train took its name from the maple leaf, the national symbol of Canada. The Maple Leaf was one of many trains discontinued when Amtrak began operations in 1971, and is unrelated to the Maple Leaf which Amtrak now operates between Toronto and New York City. The train operated on Canadian National railroad territory through Ontario, but west of Lake Huron it operated via Grand Trunk Railroad.
