Pointe-du-Buisson is actually a collection of 16 archaeological sites which opened to the public in 1986. Exhibits here include all sorts of fascinating finds from the site, dating to regional aboriginal people from 5000 years ago up through the mid-1900s. Along with the dig sites and museum exhibits there is a traditional sugar shack and a couple of kilometers of trails. Initial digs here led to the Université de Montréal becoming the first accredited archaeology school in the province. For an additional fee, you can even take part in one of the ongoing digs.

This museum on the campus of McGill University features a wide range of fossils (including dinosaurs!), skeletons of rare and extinct animals, rocks and minerals, and a fine collection of Egyptian antiquities. A very worthwhile place to visit.
