Wiejący wiatr powoduje niewielkie, zamierzone odchyły konstrukcji. Przy wietrze wiejącym z prędkością 190 km/h poziomy restauracji od pionu odchylają się o około 30 cm (chociaż w Sky Podzie, opisanym poniżej, wyraźne kołysanie da się odczuć już przy wietrze o prędkości 60 km/h, w przypadku odchyłów od osi na odległość większą niż 1 metr ze względów bezpieczeństwa poziom jest zamykany). Podwójne kuloodporne szyby w wyższych partiach wieży mają 6,4 i 9,5 mm grubości.
The CN Tower consists of several substructures. The main portion of the tower is a hollow concrete hexagonal pillar containing the six elevators, stairwells, and power and plumbing connections. On top of this is a 102-metre tall metal broadcast antenna, carrying TV and radio signals. There are two visitor areas: the main deck level (formerly known as SkyPod) located at 346 metres, and the higher Sky Pod (formerly known as "Space Deck") at 446.5 metres, just below the metal antenna. The hexagonal shape can be seen between the two areas; however, below the main deck, three large supporting legs give the tower the appearance of a large tripod.

The main level is seven stories, some of which are open to the public. Below the public areas — at 338 metres — is a large white donut-shaped radome containing the structure's microwave receivers. The glass floor and outdoor observation deck are at 342 metres (1,122.0 ft). The glass floor has an area of 24 square metres (258 sq ft) and can withstand a pressure of 4,100 kilopascals (595 psi). The floor's thermal glass units are 64 millimetres (2.5 in) thick, consisting of a pane of 25-millimetre (1.0 in) laminated glass, 25 millimetres (1.0 in) airspace and a pane of 13-millimetre (0.5 in) laminated glass. Some people experience acrophobia when standing on the glass floor and looking down at the ground 342 metres below. In 2008, one elevator was upgraded to add a glass floor panel, believed to have the highest vertical rise of any elevator equipped with this feature. The Horizons Cafe and the lookout level are at 346 metres . The 360 Restaurant, a revolving restaurant that completes a full rotation once every 72 minutes, is at 351 metres. When the tower first opened, it also featured a disco named Sparkles, billed as the highest disco and dance floor in the world.

The Sky Pod is the second-highest public observation deck in the world, surpassed only by the Shanghai World Financial Center. On a clear day, it is possible to see 100 to 120 kilometres (62–75 mi) away, to the city of Rochester across Lake Ontario in the United States, the mist rising from Niagara Falls, or the shores of Lake Simcoe.[citation needed]

A metal staircase reaches the main deck level after 1,776 steps, and the Sky Pod 100 metres above after 2,579 steps; it is the tallest metal staircase on Earth.[citation needed] These stairs are intended for emergency use only and are not open to the public, except for three times per year for charity stair-climb events. The average climber takes approximately 30 minutes to climb to the base of the radome, but the fastest climb on record is 7 minutes and 52 seconds in 1989 by Brendan Keenoy, an Ontario Provincial Police Officer. In 2002, Canadian Olympian and Paralympic champion Jeff Adams climbed the stairs of the tower in a specially designed wheelchair.
