The Canada Permanent Trust Building is designated to be of architectural value as being one of the finest highrise bank buildings of its period in Canada. Designed using the simplified classical forms of the Style Moderne, it combines an emphasis on its vertical height appropriate to its basic form, with the impressive vaulted banking hall, characteristic of bank buildings at the beginning of the Century. The building is also important as a part of the Bay Street canyon of high-rise buildings that has come to be regarded as symbolic of Toronto's financial quarter."
