I always enjoy a little adventure, so this was the perfect activity. For CAD $225 (US $179.45), you get to walk around the edge of the CN tower for about 45 minutes. I thought it was a little expensive, but the exchange rates made it just a little better. (woohoo US currency...)
If you wanna bring your GoPro and take some Instagram worthy photos, be ready to count on your tour guide to be your designated IG photographer. And yes, it's another CAD $25 to get all your photos from the experience on a USB stick. If you don't pay the $25, it's just a print of you at the edge and a group shot of you and the other people in your group plus a DVD with a video of the highlights in the 45 minutes.
As for teenagers, the requirement is at least 13 years old.
My guide's name was Colin. He was a cool guy. Except I feel like he has done so many edge walk tours, he needs to boost his enthusiasm a little more instead of sounding like a happy recording tape.
Overall, this was a fun experience and I would go back sometime in the winter just to see what Toronto looks like during that season.
