More Information

Notable modern elements of 333 Portage Avenue include the use of Manitoba Tyndall limestone facing and lack of exterior ornamentation. The relatively conservative height of the building is also characteristic of many of Green Blankstein Russell buildings of this period. In 2015 the building underwent an extensive renovation to become studio space for cable television station APTN.
