The “PATH” is truly an amazing feature of Toronto. I never really appreciated this urban marvel until I had to do a project for Marketing Geography (great course BTW), in which we had to analyze the stores from a section of PATH. The PATH stretches for 27 km, and has over a 1000 shops. If you’re new to Toronto, I highly suggest you take a stroll during the afternoon, for more details check out http://www.toronto.ca/path/
