The Haineault Mont Saint-Hilaire Collection is the premiere collection of Mont Saint-Hilaire minerals in the world.

The Mont Saint-Hilaire intrusion is unique on the planet and has been a destination for mineral collectors and mineralogists from around the world for over 50 years because more than 420 distinct mineral species have been found there.
