7. Toronto, Canada
Toronto is a meeting place, a crossroads of many cultures and ethnicities. Toronto is downtown Canada, the biggest city in the country with a skyline to match. Toronto has 7 structures in its skyline that stand at over 200 metres, including the astonishingly tall 553 metres, CN Tower, which is often referred to as the tallest freestanding structure in the world. While mostly untrue (because there are taller TV masts in the world), the CN Tower possesses the world's highest observation deck, making this city's skyline one of the most immediately identifiable.
Metro/Urban Population: 5.1 million
