Ontario Fishing Regulations
A plain-English guide to Ontario’s fishing rules — licences, seasons, limits, and the things most people get wrong. Always verify with official sources before you head out.
What Are Fisheries Management Zones?
Ontario divides the province into 20 Fisheries Management Zones (FMZs). Each zone has its own set of rules — different seasons, catch limits, and size restrictions depending on the fish populations in that area.
Before you fish any water in Ontario, you need to know two things: which FMZ you’re in and what the rules are for that zone. Some lakes even have waterbody-specific exceptions on top of the zone rules.
You can find your zone using the official FMZ map or the Fish ON-Line interactive map.
Ontario Fishing Licences
To fish legally in Ontario, you need an Outdoors Card plus a fishing licence (also spelled "license" south of the border). There are two types of licence, and the one you pick determines how many fish you can keep.
Sport vs. Conservation Licence
A Sport licence gives you higher daily catch limits. A Conservation licence costs less but comes with lower limits. Both follow the same season dates — the only difference is how many fish you’re allowed to keep.
Who Doesn’t Need a Licence?
- Canadian residents under 18 — fish for free, conservation limits apply
- Canadian residents 65 and older — fish for free, conservation limits apply
- Veterans and active Canadian Armed Forces members — free with sport limits (since 2019)
- Persons with disabilities (under the AODA definition)
- Indigenous peoples exercising Aboriginal or treaty rights
Even if you’re exempt, you still need to carry government-issued ID that proves your age or status. And all other regulations still apply — seasons, sizes, gear restrictions, everything.

The Closed Season Myth
This is the one rule I hear people get wrong more than any other, and it can cost you a hefty fine.
This is wrong. In Ontario, “fishing for” a species means targeting that species — not just keeping them. If the season is closed for bass and you’re throwing topwater lures in a known bass spot in May, you’re targeting bass. It doesn’t matter that you plan to release them.
What “Targeting” Actually Means
The Ontario Ministry of Natural Resources considers several factors when determining if you’re targeting an out-of-season species:
- Your gear — are you using lures or bait that primarily attract that species?
- Your location — are you fishing a known habitat for that species?
- Your technique — does your presentation specifically target that species?
The Gray Area
Sometimes you genuinely catch an out-of-season species by accident. You’re carp fishing with corn on the bottom and a bass picks it up. That happens. Release it immediately and carefully — you’re fine.
The difference is intent. An accidental catch while legitimately fishing for an in-season species is not the same as deliberately targeting a closed species with plans to release them.
Bass season in most of southern Ontario doesn’t open until the 4th Saturday in June. It’s May and you’re casting topwater poppers along a shoreline full of spawning smallmouth. Even if you release every fish, you’re targeting bass during a closed season. That’s a violation.
Free Fishing Events in Ontario (2026)
Ontario runs several Family Fishing events throughout the year where Canadian residents can fish without buying a licence. These are a great way to get kids or newcomers on the water for the first time.
| Event | Dates |
|---|---|
| Family Fishing Weekend | February 14–16, 2026 |
| Mother’s Day Weekend | May 9–10, 2026 |
| Father’s Day Weekend | June 20–21, 2026 |
| Family Fishing Week | June 27 – July 5, 2026 |
During these events, conservation limits apply and you must carry government-issued ID. All other regulations — seasons, size limits, gear restrictions — still apply. Ontario’s TackleShare program also offers free rod and reel loans at provincial parks, conservation authorities, and some libraries.
Dog Lake, Missanabie — FMZ 7
Dog Lake sits in Fisheries Management Zone 7, up in Northern Ontario near Missanabie. This is a big, remote lake with serious fishing — walleye, pike, smallmouth bass, lake trout, and brook trout. I’ve spent time on this water and it’s the kind of place that reminds you what fishing is supposed to be.
Season Dates & Catch Limits
| Species | Open Season | Sport | Conservation | Size Restrictions |
|---|---|---|---|---|
| Walleye | Jan 1–Apr 14; 3rd Sat May–Dec 31 | 4 | 2 | Max 1 over 46 cm |
| Smallmouth Bass | Open all year | 6 | 2 | None |
| Northern Pike | Open all year | 6 | 2 | Max 2 over 61 cm (max 1 over 86 cm) |
| Lake Trout | Jan 1–Sep 30 | 2 | 1 | None |
| Brook Trout | Jan 1–Labour Day | 5 | 2 | Max 2 over 30 cm (max 1 over 40 cm) |
Fish Sanctuaries on Dog Lake
Dog Lake has several areas that are closed to all fishing at certain times of year. These protect spawning grounds — respect them.
Bay 57 Narrows (West Township) — no fishing at any time.
Dog-McMurtry Narrows (Bruyere Township) — no fishing at any time.
Dog River mouth (West Township) — 200 m from river mouth.
McKee Creek, Bay 57 (Stover Township) — 200 m from creek mouth.
Height of Land Bay (Stover Township) — 1.3 km into lake.
Lochalsh Bay & Lochalsh River (Gutelius/Riggs Townships) — 182 m radius from CPR bridge.
Dog Lake is also in the Central Bait Management Zone — you cannot transport live or dead baitfish or leeches into or out of the zone.
Doe Lake, Katrine — FMZ 15
Doe Lake near Katrine is where it all started for me. It sits in Fisheries Management Zone 15, in the heart of cottage country. This lake follows the standard FMZ 15 zone rules — no waterbody-specific exceptions apply.
Note: There is another Doe Lake in FMZ 15 (near Minden Hills in Anson Township, about 80 km south) that has different rules for brook trout. Make sure you’re looking at the right one.
Season Dates & Catch Limits
| Species | Open Season | Sport | Conservation | Size Restrictions |
|---|---|---|---|---|
| Walleye / Sauger | Jan 1–Mar 15; 3rd Sat May–Dec 31 | 4 | 2 | Max 1 over 46 cm |
| Bass (Largemouth / Smallmouth) | 4th Sat June–Nov 30 | 6 | 2 | None |
| Northern Pike | Jan 1–Mar 31; 3rd Sat May–Dec 31 | 6 | 2 | None |
| Lake Trout | Jan 1–Sep 30 | 2 | 1 | None |
| Yellow Perch | Open all year | 50 | 25 | None |
FMZ 15 is also in the Central Bait Management Zone — same baitfish restrictions as FMZ 7.
Grand River — FMZ 16
The Grand River is one of the most popular fishing rivers in Ontario. It runs from Belwood Lake all the way down to Lake Erie, passing through Elora, Fergus, Kitchener-Waterloo, Cambridge, Paris, Brantford, and Haldimand County along the way.
The regulations change significantly from section to section. The upper Grand near Elora is a protected trout fishery with strict catch-and-release rules and barbless-only gear. By the time you get to Haldimand County near Lake Erie, the rules are completely different.
I’ve fished this river from one end to the other, and the biggest mistake people make is assuming the rules are the same everywhere. They’re not.
