I doubt Fort Edmonton Park could find the space for a wooden roller coaster but it sure would be cool (and historically accurate)! The roller coaster at Borden Park (AKA: East End City Park and Exhibition Park) was built in 1915 by the Lynn Welcher Construction Co of New York and dismantled in 1935. You can read more about the roller coaster and midway at Coaster Enthusiasts of Canada.
