Bonar Creek was a tributary of Mimico Creek, a watercourse that empties into Lake Ontario in the former city of Mimico, now part of Toronto, Ontario, Canada. Bonar Creek joined Mimico Creek 130 metres (430 ft) north of Lake Shore Boulevard, in the marsh at the mouth of the Mimico Creek.
Almost the entire creek has been buried, except for a short stretch where the former watercourse joined Mimico Creek, and that remaining portion has been canalized. However there are plans to restore part of the wetlands at the confluence of the two creeks.
Mimico Creek Watershed
The Origin of the Watershed's Name: "Mimico" comes from the Algonkian word "Omimeca" meaning "resting place of wild pigeons". The extinct passenger pigeon used the mouth of Mimico Creek as a migratory stopover.
The Mimico watershed is a completely urbanized watershed within Toronto and Region Conservation's jurisdiction, with over 30% of its landmass featuring industrial land-uses and over 60% of its reach artificially channelized. As a watershed shaped so extensively by human intervention, its management requires close attention to the protection, enhancement and expansion of its remaining natural systems and the improvement of its water quality by improving and limiting urban storm water runoff.
Humber Bay Park on Toronto's waterfront is often mistaken as the mouth of the Humber River, but is in fact the mouth of Mimico Creek. Up until the 1970s, when the two large landfill parks (Humber Bay Parks East and West) were constructed on either side of the Mimico's mouth, the creek flowed directly into the lake below Lake Shore Boulevard West.
