Chipmunk in the Don river valley

I saw this chipmunk running over the trail along the river (which is paved in asphalt, by the way). These creatures are so fast and agile, that I was convinced I would not see it anymore. But there it was, just sitting on this tree.
I think it is just unbelievable that wildlife like this can be found in the centre of Canada's largest urban development, at walking distance from Bay Street, the economic centre of the country.
