University Avenue has matured and mellowed somewhat since Berton's unfavourable observation, though paving is still characterized by poured concrete and asphalt for most sidewalks and roadway. Restaurants now dot the southern end of University Avenue. Recently completed at the intersection of University and Queen Street is the Four Seasons Centre, which is the new home of the Canadian Opera Company and the National Ballet of Canada. Osgoode Hall presents stately architecture and a welcome green space. During the holiday season, festive lights illuminate the trees and shrubs of the boulevard. Unlike most major streets in Toronto, there are no rooftop billboards visible from University Avenue due to a bylaw.
