Wildlife Viewing.
Two distinct urban wildlife spectacles run on Mississauga's calendar: the Credit River fall chinook salmon ascent (September–October) at in-city overlooks at Streetsville Memorial Park and Erindale Park, and the spring/fall bird migration through the Rattray Marsh coastal wetland — the only remaining lakefront marsh on the Canadian shore of Lake Ontario between Toronto and Burlington, on the Atlantic Flyway.
The brief.
The Credit River chinook ascent peaks late September through mid-October; visibility is best from the river-edge overlooks at Streetsville Memorial Park (Queen Street South) and Erindale Park (Mississauga Road bridge area), with fish holding in pools and running riffles between rains. Steelhead follow in the spring (March through May).
The chinook viewing crowds peak on warm October weekends; weekday mornings are quieter. At Rattray Marsh, spring waterfowl peaks late March through April; fall passerine and shorebird migration is September through October.
The boardwalk loop is roughly 1 km; bring binoculars. Lakefront Promenade Park's sheltered lagoons hold wintering ducks (long-tailed, common goldeneye, mergansers) when most other lakefront freshwater freezes.
All sites are free entry and accessible by MiWay transit.
