Queen Mary Road crosses the borough of Côte-des-Neiges-Notre-Dame-de-Grace and the town of Hampstead and is located on the northwest flank of Mount Royal.

The road was named in 1910 in honour of Mary of Teck, who became Queen consort on May 6, 1910, when her husband George V became King of the United Kingdom.

The development of public transportation encouraged the construction of numerous tenements along major thoroughfares such as Queen Mary Road, which was then the Snowdon Junction terminus.

[1] In the 1960s, the Decarie Expressway trench was dug, splitting the road in two, which increased vehicular traffic in the Snowdon neighbourhood.

Today, Queen Mary Road is still a main focus of the neighbourhood.
