While the two previous special exhibits at the Canadian Museum of History wrapped up in early January, there's a third one that is ongoing until early next year. Horse Power has been done in collaboration with the Musees de la Civilization in Quebec City, showing horse drawn sleighs and carriages of the 19th century.
Visible from this exhibit is an adjacent balcony that I think must be used with school groups as a sort of jumping off point for tours. That's how it feels to me, anyway, and I believe it's accessible from an area of the Museum referred to as the Canadian Children's Museum. Yes, I have been in there on two different occasions. And for the record, both times I ended up coming out with splitting headaches.
Children are loud.
