The April 16 1930 edition of the Toronto Daily Star contained this ad that recommended that buildings be constructed with an extensive use of copper, brass, and bronze:
I looked up the Copper & Brass Research Association in the Toronto city directories. In the 1930 directory, they were on the 10th floor of the building at 67 Yonge Street. In 1931, they had moved to the 12th floor of the building, and were sharing space with Lord, Thomas, and Logan, an advertising agency. Not sure whether the agency bought out the association, the association expanded to become an agency, or the two just joined forces.
By 1936, the advertising agency was called Lord & Thomas of Canada, Limited. (I’m not sure what happened to Logan.) The Copper & Brass Research Association was also still listed at 67 Yonge. But, by 1938, only the advertising agency was listed.
67 Yonge Street still stands; it’s a nice-looking old building. It is a fifteen-story building that, in the 1930s directories, actually had a listed 13th floor, instead of skipping 13 for superstitious reasons. I checked, and there was a 13th floor as late as 1960; I couldn’t find any information on whether they now skip that number. (The property owner’s website for the building doesn’t list its tenants.) When we’re allowed to move about freely again, I’ll have to check the office directory to see whether 13 is now skipped.
