Ice Fishing in Ontario: Seasons by Zone, Hut Rules and Ice Safety

Ontario never opens or closes an "ice fishing season". The province says so plainly: there are only fishing seasons, and whether you fish them from a boat, the shore or a hole in the ice depends on the weather. That makes a winter trip a matter of reading two things for the lake you have in mind: the open seasons of its Fisheries Management Zone, and any rule the regulations summary lists for that lake by name. This guide walks through both, then the hut, line and safety rules that only matter once there is ice.

What closes through the winter, and where

The seasons below come from the zone-wide tables of the 2026 Ontario Fishing Regulations Summary, read for December 1 to March 31. Our ice fishing by zone page lays all 20 zones side by side and recalculates the dates every winter; each zone page has the limits and the exceptions.

Walleye and sauger are open the whole ice season across the north (Zones 1 to 9, 12 and 13) and on Lake Erie (Zone 19). Further south the season ends before the ice does: the third Sunday in March in Zones 10 and 11, March 15 in Zones 15 and 16, and March 1 in Zones 14, 18 and 20. In Zone 17, the Kawarthas and the Trent-Severn lakes, walleye stay closed all winter.
Lake trout are closed in December in most inland zones and open on January 1, so January 1 is the lake trout opener on inland lakes from Haliburton to Thunder Bay. Zone 8 opens only from February 15 to March 15, Zone 11 from February 15 to the third Sunday in March, and Zones 17 and 18 keep lake trout closed through the ice. The Great Lakes zones (13, 14, 19 and 20) and Zone 1 are open all winter.
Brook trout mostly follow lake trout and open January 1, but they stay closed all winter in Zones 6, 9, 12, 16 and 17. The 2026 summary also lists nearly 600 lakes in ten zones as "additional fishing opportunities" where brook trout stay open all year; the zone pages list them.
Northern pike, yellow perch and lake whitefish are the reliable winter species: open all season almost everywhere. The exceptions are pike in Zone 11 (to the third Sunday in March) and Zone 14 (to March 1), and whitefish in Zone 17, where it is closed.
Muskellunge close on December 15 in every zone that has them, so a muskie through early ice is legal for two weeks at most. Bass are closed through the winter in most of the south and open in the northern Zones 2 to 9.

Two caveats. First, Ontario publishes a new summary every January 1, so dates after December 31 can change mid-winter; re-check in January. Second, the table is zone-wide. It applies to every lake in the zone except the ones the summary lists, and the south has a lot of those.

The big ice fisheries have their own rules

The lakes that draw the most huts are exactly the ones with lake-specific regulations, so the zone table alone will mislead you there. From the 2026 summary:

Lake Simcoe and Lake Couchiching (Zone 16): lake trout, lake whitefish and lake herring (cisco) are open January 1 to March 15, then not again until the second Saturday in May. Whitefish and cisco carry limits of 2 on a sport licence and 1 on a conservation licence. Yellow perch are S-50 a day with a possession limit of 100 (C-25 and 50). Muskellunge are closed all year.
Lake Nipissing (Zone 11): the lake, its west arm and the lower reaches of its rivers are closed to all species from December 1 to December 31 and again from March 16. Walleye and perch open January 1; walleye are S-2 and C-1, and every walleye kept must measure 40 to 45 cm. Commercial and tourist hut operations on Nipissing also need a special licence.
Lake of the Woods (Zone 5): outside Clearwater Bay, lake trout carry a limit of zero, so they are catch and release. Walleye have their own slot (on a sport licence, Canadian residents keep none between 43 and 70 cm), and bays such as Whitefish Bay and Echo Bay add bait and barbless-hook rules; read the waterbody exceptions before you go.
Lake Scugog (Zone 17): walleye are closed all year, and the 100 metres either side of the Highway 7A crossing are a fish sanctuary from November 16 to the Friday before the second Saturday in May.

On every lake page of this site, an "Ice fishing" panel shows the zone-wide table for that lake and flags any rule the summary lists for it by name and location. Treat it as a starting point and read the official text for the lake before you drill.

Ice huts: registration and removal

You must register an ice hut in Zones 9 to 12 and 14 to 20 if it is made of anything other than fabric, or if it is a fabric tent covering 7 square metres (75.4 sq ft) or more when set up. Pop-up shelters under that size, and every hut in Zones 1 to 8 and 13, are exempt. Registration is free, done once, and needs no Outdoors Card: apply online through the Fish and Wildlife Licensing Service or in person at a participating ServiceOntario centre. One number covers all the huts you own, and it goes on the outside of each hut in characters at least 6.3 cm (2.5 in) high. Numbers issued before September 20, 2023 remain valid, but updating the contact details on one means registering for a new number.

Removal dates depend on the zone:

March 1: Zones 17 and 20
March 15: Zones 14, 16, 18 and 19, and Zone 12 below the Lake Timiskaming dam
March 31: Zones 9, 10, 11 and 15, and Zone 12 above the dam

Every hut, in every zone, must also be off before the ice breaks up, even when no date applies or the date has not come. The ministry is blunt that removal is a safety deadline, not the end of fishing: you can keep fishing from the ice after your hut is off, if the ice allows it. Ontario's natural resources ministry has warned that failing to remove a hut on time can bring charges of up to $15,000 for a first offence, and in March 2026 an angler from north-eastern Ontario was fined $3,000 for several ice fishing violations, including abandoning a hut on a lake.

Inside a provincial park, a hut may need the park's own authorization on top of all this. Ask the park office before hauling one in.

Lines, tip-ups and gear

Through the ice you may fish with two lines in most waters, as long as you stay within 60 metres of every line or tip-up and have a clear view of all of them. Open water is one line unless a zone says otherwise, so the two-line allowance is one of the few rules that is genuinely ice-specific. Some lakes cut it back: several lake trout lakes in Zone 15 carry the gear restriction "only 1 line may be used when angling through the ice, regardless of what species is/are being targeted", and that rule binds even if you are jigging for perch. The zone pages list those lakes.

A spring-loaded hook setter (any device that uses a mechanical spring to set the hook, other than a rod under tension) may not even be brought within 30 metres of the water. Tip-ups that simply flag a bite are fine; the spring-set versions are not.

Bait and licences, briefly

The fishing licence and zones guide covers both in full. The winter points: baitfish and leeches, live or dead, cannot leave or enter one of Ontario's four Bait Management Zones (salted or otherwise preserved bait excepted), so buy minnows from a dealer near the lake and keep the receipt; and a long list of lakes bans live bait outright, including every lake in Algonquin Park. The licence rules do not change in winter. Canadian residents can fish without a licence during Family Fishing Weekend in February (February 14 to 16 in 2026), under conservation limits; anyone under 18 or 65 and older needs no licence at any time, only ID.

Reading the ice

No regulation makes ice safe. Ontario's own guidance for clear blue ice is at least 20 cm (8 in) for a snowmobile and 30 cm (12 in) or more for a light vehicle, doubled when the ice is white or opaque. The Canadian Red Cross uses its "15-20-25" rule: 15 cm for walking or skating alone, 20 cm for skating parties or games, 25 cm for a snowmobile. Use the higher number when in doubt.

Ice does not freeze evenly. Near-shore ice is often much thicker than ice further out, especially early in the season, so check with a spud bar or auger as you go, not once at the shore.
Ice over moving water, springs, pressure cracks, old holes and the mouths of rivers and creeks can be far weaker than the ice around it. Narrows between basins are classic trouble spots.
Heavy snow on a lake slows freezing and hides slush. Honeycombed, grey ice in a thaw or in spring is weak whatever its thickness.
Ask the local hut operators or the anglers already on the lake about the ice, as the province itself recommends.
Carry ice picks around your neck, wear a floatation suit or PFD when the ice is uncertain, and tell someone which lake and access you are using and when you will be back.

Where to go

Each zone page lists the surveyed lakes in that zone with the game fish recorded in government surveys and the deepest contour on the provincial depth chart, which is a better starting point for a lake trout or whitefish trip than any rumour. If you want a warm car park and a short walk, several provincial parks open in winter sit on fishable lakes, and Crown land around them lets you camp free on the shore or the ice under the 21-day rule.
