Freshwater Fishing.
The Credit River within Mississauga sits in Fisheries Management Zone 16 (Lake Ontario tributaries), with extended migratory seasons for chinook salmon (September–October), brown trout, and steelhead (March–May) running between Lake Ontario and the Caledon hills upstream. The Lake Ontario shoreline falls in FMZ 20: year-round Atlantic salmon and the standard Great Lakes calendar for bass and walleye.
The brief.
Credit River access in Mississauga runs from the river mouth at Port Credit upstream through Erindale Park and the Culham Trail to Streetsville Memorial Park. FMZ 16 sanctuary closures apply on specific Credit River reaches during migratory windows; check the year-specific Ontario Fishing Regulations Summary FMZ 16 page for the current dates and the one-trout daily limit details.
The lower-river chinook ascent (peak late September through mid-October) draws crowds at Streetsville and Erindale; the spring steelhead run (March through May) is quieter but technically demanding. On the lake side, FMZ 20 carries year-round Atlantic salmon (must exceed 63 cm), bass open with the Great Lakes calendar from late June, and walleye January through March and May through December; lake trout open January through September plus December.
Shore and pier access at Port Credit and Lakefront Promenade is open year-round. A valid Ontario fishing licence is required for both zones.
