I usually give museums and cultural establishments five star reviews, bit this is one place I really cannot justify it. It is a very neat building from the outside, but that is just about it. This is supposed to be a museum geared towards the environmental, but is is so sparse, there are just four rooms, one of which is a 4D movie, another some activities for the kiddies, and the other two are just as uninteresting. Very boring stuff (to me)
On the top floor there's an observatory where you can see Montreal from all angles and this is what made the $15 admission a little for me. The view was great. Other than that, nothing special about this place.
