The Public Service Alliance of Canada Building is a modernist elliptical office building in Ottawa, Ontario, constructed in 1968 as the national headquarters for the Public Service Alliance of Canada. Designed by Paul Schoeler of Schoeler & Heaton Architects, the 12 storey building is located at the intersection of Gilmour and Metcalfe.
