The CN tower is a beautiful landmark building but I must admit, it's a total tourist trap. I much prefer looking AT the CN tower rather than looking from it.
General tickets are $35 and it includes a 58-second elevator ride to the indoors lookout/observation level, the glassfloor and the outdoors sky terrace, and two 15-min films at the Attractions level about the Red Rocket (Toronto's bus system) and the construction of the CN tower.
