Zone-wide, brook trout season is January 1 to Labour Day (Jan 1 – Sep 7 in 2026). Some rivers have species exceptions or sanctuaries listed on this page that change this.

The table above shows which species are open today under the zone-wide seasons. A specific river or lake may differ, so check its species exceptions, waterbody exceptions and sanctuaries below before you go.

Most anglers need an Outdoors Card and a valid fishing licence (sport or conservation). Some people are exempt, such as Ontario residents under 18 or 65 and over. Check the official licensing rules for your situation.

Ontario's Fisheries Management Zones are mapped on Fish ON-Line and in the official summary. River mouths on the Great Lakes are often in a different zone from the rest of the river.
