It was built by architect Ernest Cormier in 1930–31 as his own residence. In 1974, the building was designated as a historical monument in Quebec.
In 1979, the property was bought by the 15th Canadian prime minister, Pierre Trudeau, for $230,000.[2] It served as his home from his retirement from politics in the summer of 1984 until his death in 2000.[3][4]
It has been owned since 2000 by his son Alexandre,[5] younger brother of the current Canadian prime minister, Justin Trudeau.
Cormier House has been designated as a historic property under Quebec's heritage legislation, the Loi sur les biens culturels.[7] The house appeared on a stamp issued by Canada Post in 2011.[8][9]
