Situated on the north shore of Lake Ontario, Toronto has distinctive neighbourhoods, where immigrants from across the globe have helped shape what it means to be Canadian. The city’s most prominent feature is the CN Tower. The landmark is one of the world’s tallest free-standing structures, and has design elements that help visitors enjoy the view. Chief among them are glass-fronted elevators and a revolving restaurant near the top. Toronto also boasts the Rogers Centre (formerly the Skydome). The multi-purpose entertainment complex has a retractable roof, and a claim to being the world’s greatest entertainment centre.
