The BMO Building was originally a Merchants Bank (full circle, eh?), built in 1915 and is listed:

Its architect was apparently aware of the work of the great 18th C French architect Claude-Nicolas Ledoux:
Hôtel d'Hallwyll, 28 rue Michel-le-Comte et 15 rue de Montmorency, Paris. Elévation de la façade sur la rue Michel-le-Comte. 1766
The architect C. J. Gibson was apparently a hard-working guy, according to the DoAC. He did the Merchant's Bank on Dundas at Roncesvalles, less successful imo. losttoronto blog says this is where the Boyd gang got started!
