If memory serves me correctly, this was a Toronto Dominion Bank when I first moved to London some decades ago. Slowly many of the core bank branches, housed in glorious older buildings, have been closed. If these buildings were to be saved, new uses for them had to be found. This one at the Dundas and Wellington Streets intersection was a tough sell.
Again, if my memory is correct, this building, which now houses the Canadian Medical Hall of Fame, was originally facing demolition. It was city owned and thought to be a bit of a classic white elephant. But it was saved, beautifully restored, and renamed the J. Allyn Taylor Building after the very interesting, very warm, very civic minded gentleman, and he was a gentleman, who headed London-based Canada Trust, retiring as president in 1979.
