One of the first things I discovered was that there are a large number of trails that run through the city along various creeks and rivers.
When you are on these trails you are barely aware that you are in the largest city in Canada. A very handy way to get a quick break from the urban noises and landscape for a while.
These are some more pictures from my days wandering:
