Mimico Creek is a short urban waterway in Toronto, Ontario, draining a heavily urbanized watershed of approximately 7,700 hectares before emptying into Lake Ontario at the Humber Bay Park complex, roughly 1.6 km west of the mouth of the Humber River. The creek originates in Brampton and runs approximately 33 km in total length, though the paddleable section near its mouth is quite brief.

The primary access point for paddlers is the small boat launch at Humber Bay Park West, located on the east side of the park adjacent to the mouth of Mimico Creek. This is a shallow entry point that provides access both northward into the creek and southward toward Lake Ontario. The area immediately south of the creek mouth, before the open lake, is well-sheltered and suitable for relaxed paddling. Heading north up the creek, the paddle is short, extending only as far as the railway tracks. The Santiago Calatrava-designed Mimico Creek Pedestrian Bridge, completed between 1996 and 1998, is a notable landmark along this stretch. The bridge spans 44 metres, has a deck 2.5 metres wide, and weighs approximately 50 tons; it was prefabricated in four pieces and assembled on site.

Humber Bay Park West offers a range of amenities relevant to paddlers, including public boat launches, mooring facilities, fishing piers, trails, seating areas, parking, and washrooms. The park also accommodates the Mimico Cruising Club, Etobicoke Yacht Club, Humber College Sailing Centre, and the Toronto Police Marine Unit.

Water quality in the Mimico Creek watershed is affected by its high degree of urbanization — approximately 89% of the watershed is classified as urban land use. Non-point source contamination from stormwater runoff is identified as the largest contributor to surface water quality issues. Paddlers should be aware of this context when considering activities such as fishing or swimming in the creek.

On calmer days when wind picks up on the lake, the creek itself offers a quieter alternative. The creek's estuary is flanked by Humber Bay Park West and Humber Bay Park East, both constructed from landfill between roughly 1970 and 1990. Fishing is a common activity at this location.
