Soaring 553 meters above downtown Toronto, the CN Tower held the title of world’s tallest free-standing structure for over three decades and remains the defining feature of the Canadian skyline. Built between 1973 and 1976 as a communications tower, it has since become one of the country’s most visited attractions, drawing over 1.5 million visitors each year to its multiple observation levels. The LookOut Level at 346 meters offers panoramic floor-to-ceiling windows and a glass floor that lets you peer straight down to the streets below, while the SkyPod at 447 meters provides views reaching as far as Niagara Falls and the Rochester shoreline on a clear day.

For those craving an adrenaline rush, the EdgeWalk — a hands-free walk along a 1.5-meter-wide ledge circling the outside of the tower’s main pod at 356 meters — is the world’s highest external walk on a building. Below the observation decks, the revolving 360 Restaurant serves elevated Canadian cuisine as the dining room completes a full rotation every 72 minutes, offering a constantly shifting panorama of the city, Lake Ontario, and the Toronto Islands.

Pro tip: Book the 360 Restaurant for dinner and your elevator admission to the observation deck is included free. Time your reservation for about 30 minutes before sunset so you can watch the city transition from daylight to a glittering carpet of lights as you dine.
