The Walter Carsen Centre for The National Ballet of Canada is a building at 470 Queen's Quay West on the waterfront in Toronto, Ontario, Canada. The lower levels house the headquarters of the National Ballet of Canada and the ballet's rehearsal space. The facility has 8,825 square metres of space, more than the Four Seasons Centre where the ballet performs. Previously the ballet had been based at St. Lawrence Hall and scattered other buildings through the downtown core.
