Apparently related to the grey not the red, the black squirrels in Toronto have adapted to retain more heat when it is cold. I imagine they suffer a bit when it is 27 degrees like today.
Although shy of the dog that really wanted to chase it, they were not at all bothered by us and wandered really close.
Although Toronto did not offer us bears- only squirrels, sparrows, pigeons and seagulls, we did get an awesome thunderstorm on our first night which gave us an excuse other than jetlag to be awake for a few hours in the early morning.
