The McCord Museum is famous for its collection of photographs. The collection started with the Notman Photographic Archives. William Notman (1826-1891) was a pioneer in photography and opened his first photography studio in Montreal in 1856. His sons continued until 1935 under the name William Notman & Son.
William Notman and his sons documented through their work an important part of history. The collection contains now more than a million photos and it keeps growing.
A small part of this huge collection of historic photos is available online at:

I would especially like to thank Anne-Frédérique Beaulieu of the McCord Museum for her time and help with the search for photos relevant to the history of Baie-D'Urfé.
Note: as of Dec 2021 the McCord Museum is working on its online presence to make changes for its 100th anniversary and the server could be offline for a while.
