The Landscapes of Canada Garden is at the Canadian Museum of Nature, having had been finished this past spring. It portrays topography and vegetation of Canada, starting with the mammoth steppe (complete with a life sized family of them in statue form), moving into Arctic tundra, Prairie grassland, and finishing with Boreal forest. It's a work in progress, as the evergreens of the Boreal section are relatively young trees (and seemingly wrapped up for the winter), but it's a delightful spot to wander. I passed through on a gloomy day a few days back. The vegetation itself, particularly the grasslands, is largely dormant now, waiting for next spring.
