Lying in the southern reaches of Etobicoke Creek, Old Hoser is a drain named for the numerous elderly gentlemen roaming the creek’s various paths. This drain, which is one of the earlier built ones on Etobicoke Creek, has an outfall that empties into a particularly deep part of the creek with a small slippery concrete slope to contend with. After navigating the slope, 1800mm arched tunnel presents itself. After many metres of lovely arched pipe, the drain transitions into slightly larger RCP which carries on a while, also decreasing in size.
