Redpath Museum in Montreal
 
While visiting Montreal for work, I had the opportunity to visit Redpath Museum, which is part of McGill University. It's a small museum on campus, but jam packed with casts, dioramas, models, and more. 

The main dinosaur on display is Gorgosaurus, and they also have a Stan T-rex skull replica. 

Definitely worth a visit if you are in the area! Admission is free, with a suggested donation of 10 CAD.
