In 1969, the heirs of Canadian railway magnate william Cornelius Van Horne put up for sale the Van Horne Mansion in Montreal, Quebec, Canada. A buyer was not found until 1973, when developer David Azrieli bought the land. His intention to raze the mansion was met with fierce opposition from many groups opposed to the demolition spree of the Golden Square Mile, including Rene Lepine, another big-time real estate developer who owned the building next to the Van Horne Mansion and who wanted to buy it back from Azrieli to restore the mansion instead of developing the land. However, Mr. Azrieli remained committed to demolishing the historic landmark, and, during the early morning hours of September 8, 1973, under the cover of darkness, he had the mansion demolished by bulldozers. Montreal residents woke the following morning to a pile of rubble where once stood the proud home. The Sofitel Montreal now stands on the property which is the building Azrieli built.
