I believe he was talking about deco towers. There are a couple, yes, but not as many as some other cities.
Were there many towers in Toronto, *period*? Look: even the tallest of all, Commerce Court North, is basically a Deco-fied Romanesque: its antecedents like Bertram Goodhue or Eliel Saarinen are clear. BNS across the street is retardataire postwar Deco; a bit to the NW is the the Saarinen-like soar of Canada Permanent; further NW still is the Concourse, and a bit to the NE is 80 Richmond, all Deco. And other than the FCP block (which claimed the Toronto Star Building and some other smaller gems), Toronto hasn't really *lost* much in the way of Deco office buildings, either--because it didn't have them in the first place.
As far as major non-Deco stuff of the Deco period, you're left with little more than Royal York and Canada Life--and even that's arguable. (Canada Life may be classical, but it's a very Lutyens-esque classical that might as well be a Deco tributary in its own right.)
