Leeblain is a ghost town in the Canadian province of Ontario, located on the north shore of Gunflint Lake in the Thunder Bay District, partly within La Verendrye Provincial Park and next to the Boundary Waters Canoe Area Wilderness in the Boundary Waters between Canada and the United States.

It was hoped that the town would grow into a "metropolis" because of the business generated by the iron mines immediately across the border in Minnesota that were part of the Gunflint Range.

The railway planned for Leeblain to be its major terminal point outside of Port Arthur, with a roundhouse and other maintenance facilities.

The town site was also used as a worker camp during the construction of the railway, and some of the Italian labourers built rock ovens to bake their bread.

[5][6] The hotel at Leeblain was operated for a time by Adolph Perras who was previously a businessman in the town of Port Arthur.
