Black Creek is an urbanized water body in the lower portion of the Humber River watershed. Sections of it have been channelized with concrete structures to convey water through the area faster, reducing flooding.
The fire hydrant is unusual as most stations just have fire extinguishers. On another note, take a close look at the concourse level ceilings – they are just wood painted blue!
