Toronto's iconic CN Tower, a marvel of 1970s engineering, looks like a giant concrete hypodermic needle. Its function as a communications tower takes a backseat to relieving tourists of as much cash possible: riding those glass elevators up the highest freestanding structure in the world (553m) is one of those things in life you just have to do. If not, you're bound to catch a glimpse of the tower at night, when the entire structure puts on a brilliant free light show year-round. Try the intersection of McCaul St and Queen St W, due north of the tower, for best vantage.
On a clear day, the views from the top are astounding; if it's hazy (often) you won't see a thing. Queues for the elevator can be up to two hours long in each direction. Buying tickets online saves 15%. There's an obligatory revolving restaurant (called 360°): it's expensive, but the elevator price is waived for diners. Cashed-up daredevils (13 years+) can now opt for the EdgeWalk, a 20-minute outdoor walk around the unbounded perimeter of the main pod (356m). Not for the fainthearted.
