It's all good until they tell you to put your toes or heels on the edge, but the tour does it right by breaking you in little by little as you make your way around the tower. At the end, you will truly feel fearless as you proclaim that you're on top of the world! Ok, maybe that's what I felt like saying. Our tour guide was great! Definitely a unique way to see the city. I'm sure it's a very touristy thing to do, but heck, it was my first visit to Toronto!
