MLSE refused to sell Maple Leaf Gardens to anyone who proposed to use it as an arena in competition with the Air Canada Centre. Among these turned down was Eugene Melnyk, owner of the Toronto St. Michael's Majors OHL hockey team and the Maple Leafs' rival team, the Ottawa Senators. Various redevelopment schemes were proposed, most notably an entertainment complex containing retail shops and cinemas (similar to the redevelopment of the Montreal Forum), but these plans were abandoned when it was discovered that the tiered arena seating was holding up the exterior walls of the building, acting as a form of interior flying buttress. If the bowl of seating were removed, therefore, the exterior walls would lose most of their support.
