Mile High Skyscrapers

The CN Tower, standing head and shoulders about all of the surrounding highrise condos and office towers, helps Toronto’s skyline stand out as one of the most easily recognizable in the country, if not the world. While it lost its (somewhat suspect) status the “world’s tallest freestanding structure” a few years ago, it’s still impressive to look at – or look down upon the city from its 346-metre high observation platform. But can you image the view from the top of a mile-high (1,600 metre) building? This short TedTalk video looks at what limited building height in the past, and why one day the sky may really be the limit.
