By showing my Presto Card (Toronto’s transit system pass) at the ticket desk, I got a 20% discount on my admission which also included the special exhibition, “It’s Alive”. I started on the 4th floor (top floor) where the “It’s Alive” exhibition was located and worked my way down. It’s a very good museum with wide variety of displays.
Be sure to pick up the map guide of the museum at the entrance. There is a gift shop and a cafe in the museum.
