The CNR’s Over/Under on Bloor Street
Detail of the Bloor-Dundas-Lansdowne area from 1892 Toronto Railway Company route map. As was the case with the 1893 Goad’s Atlas plate reproduced below, the area, while subdivided, had not yet become a hot spot for development. Source:

Northwest Toronto was to be filled with grade separation projects and this map illustrates clearly one of the reasons negotiations between the City, CPR, and CNR spent 15 months in front of the Board of Railway Commissioners. The one I’m interested in is the one on Bloor at Lansdowne. Source: The Globe, May 10, 1924, p. 14.

Apparently, that entire section of Bloor Street West between Lansdowne Avenue and Dundas Street West had to wait for streetcar service only until the two railway underpasses could be built.
To the relief of many the subway was nearing completion by June 1925. Image: The Globe, June 2, 1925, p. 13.
