The tallest telecommunication tower in the world, 1815' ft.
Fee $35, to see the whole Toronto from above.
Please buy the City Pass, only $55, you can access to 5 different places, including CN Tower.
In the tower, there is a glass floor which you can stand and see directly to the ground below you.
If you want to pay more for more excitement, you can go outside to the edge of the tower to test your heart and knees
Yes, I would recommend it for the first timer.
