This planetarium is unique in that it has two shows: one show is a music and visual representation of space, and the other is your standard planetarium presentation. The shows complement each other very nicely. The planetarium also has some high quality interactive displays with information about the science of space. If you are going to purchase tickets to the Planetarium as part of a package (i.e. with the Biodome, Insectarium, Botanical Gardens, or Olympic Stadium), I would recommend purchasing online or at the Planetarium directly as they list the show times that are available and the language of the shows (shows are either French or English).
