Starting in 1931, the lands located opposite the Lachine Rapids on the former Ogilvie farm were used as an aerodrome for light aircraft—but only for a few years. Around 1935, Ogilvie Manor became the LaSalle Golf Club and then, around 1943, the Alepin family purchased the 18-hole golf course and its clubhouse, which would become a place of celebration over the years, and especially for weddings.
In 1971, the LaSalle Golf Club closed for good. Ogilvie Manor no longer welcomed any visitors. The Alepin family, the owners of these premises, signed a lease with Jean-Paul Laramée in order to ensure a presence on site to protect Ogilvie Manor.
In 1980, the Québec government granted financial assistance to enable the City of LaSalle to purchase the lands between Boulevard Bishop-Power and 31st Avenue, along Boulevard LaSalle. The purpose of the acquisition of that tract of land was to realign this boulevard. According to the plans, Ogilvie Manor would be in the path of the new Boulevard LaSalle.
Pierre-F. McDuff, President of the Société historique Cavelier de LaSalle, Marcel Beaudet and other members tried to save the building. Two weeks before being granted a classification of heritage protection by the Québec government's Ministère des Affaires culturelles, on February 1, 1981, a fire broke out—a case of arson—destroying this testimony to a beautiful era.
