Cormier House (French: Maison Ernest-Cormier) is an Art Deco residence located at 1418 Pine Avenue West in the Golden Square Mile area of Montreal, Quebec, Canada.

[3][4] It has been owned since 2000 by his son Alexandre,[5] younger brother of the current Canadian prime minister, Justin Trudeau.

Cormier experimented with a variety of styles in the house: Art Deco on the facade, monumental on one side, and more modernist in the back.

Cormier created most of the furniture, with remaining pieces acquired at the 1925 Exposition Internationale des Arts Décoratifs et Industriels Modernes in Paris.

[6] Cormier House has been designated as a historic property under Quebec's heritage legislation, the Loi sur les biens culturels.
