Same man. The Herald Building, Southam Tower, CP Station, the Burns Mansion, Burns Block, the Bijou, St. George's Bandstand, the Hotel York, Department of Natural Resources Building, Beveridge Block, Wales Hotel, The Central Market (very similar to St. Lawrence Market).
Something not many people know is that Exhibition Park (now Stampede Park) had buildings very similar to those at Toronto's Exhibition Place.
The worst part is, virtually every building listed in this post was replaced by some soulless 70s/80s office insular office nightmare. Or even worse, today's Stampede Park.
