The image above shows the 3rd incarnation (I think) of the YMCA in the City of Vancouver. (The first and second buildings were on Hastings, just east of Cambie Street).
The 1941 photo of the Y was probably one of the final images taken at this location. By late 1940, the next building (on Burrard at Barclay, just behind First Baptist Church) was nearly finished.
Today, the YMCA remains at Burrard and Barclay, but it has changed. As of 2010, it became known as the Robert Lee YMCA (after the Vancouver philanthropist and major benefactor of the Y). While the City of Vancouver required that the facade of the 1940 building be retained, the interior was gutted and utterly transformed and enlarged, and an enormous condo tower was attached to help finance the changes.
