With a view 342 m (1,122 ft) straight down, even those not afraid of heights might need a little help. Think you can handle it? Wait till you get here and see if you feel the same way.

The Glass Floor has been specifically designed for you to have fun on it, so walk or crawl across it, sit on it or even jump on it. Don't worry it won't break.  The Glass Floor was the world's first when it opened on June 26, 1994.

The floor is 23.8 square metres (256 sq. ft) of solid glass that is five times stronger than the required weight bearing standard for commercial floors. It can actually withstand the weight of 35 moose.

The CN Tower's Glass Floor is a unique experience that has inspired an international bucket list of see-through floor experiences including the Grand Canyon Skywalk, Chicago's Ledge, and many more.

Also on this level, be sure to check out the Outdoor SkyTerrace. Feel the breeze at 342m (1,122 ft) above the ground.

Please note the Outdoor Terrace is currently closed. We are undergoing a renovation to modernize the Outdoor Terrace Level for enhanced accessibility that guests can enjoy year-round.
