That 5 minute walk ring seems way off, especially if you are actually in the PATH and walking through it, as implied by that map. Perhaps, if you were on the surface, and you could walk unobstructed in any direction, it would work, but the built form of the city and PATH is not at all like that. At a brisk walking pace, with no other pedestrians bumbling around in your way (good luck with that on a weekday in the PATH), you are not getting from there to Union subway station in 5 minutes, by any route. Even on the surface it's a challenge with clogged sidewalks and waits at traffic lights."Now arriving at Osgoode. The next station is: Osgoode"
