The St. John's Fog Devils were a junior ice hockey team in the Eastern Division of the Quebec Major Junior Hockey League. They were based in St. John's, Newfoundland and Labrador, and played out of Mile One Centre. The QMJHL expanded to St. John's to fill the void created by the departure of the American Hockey League's St. John's Maple Leafs, when the Maple Leafs moved to Toronto, Ontario, to become the Toronto Marlies after the 2004–05 season. The team announced their relocation to become the Montreal Junior Hockey Club on March 10, 2008.
