This monument to the brave of Outremont was unveiled on 27 July 1925 by Field Marshal Douglas Haig, commander-in-chief of the British forces in France in the later stages of the First World War. The Outremont alderman who headed the fundraising committee, Ernest Walter Sayer, could not raise enough money to build it, so he paid for it himself. It is inscribed with the motto Gloria Victoribus, and the names of Outremont's war dead, including those of the Second World War. The monument features an allegorical bronze figure of Peace putting grief behind her.
Architect John Roxborough Smith collaborated with the prominent Montreal sculptor Henri Hebert on the design of the Outremont War Memorial in 1935. Henri Hebert, son of sculptor Louis-Philippe Hébert, was born in Montréal in 1884. He studied at the Monument national de Montréal under painter Edmond Dyonnet and at the Art Association with William Brymner, as well as studying under Thomas and Injalbert in Paris.
