The ice season where the ice is safe: small spoons and tungsten jigs tipped with minnow heads, moving hole to hole to find the school.

Lake Simcoe: lake trout, whitefish and perch through the ice until mid-March, and summer bass and perch, on a big lake between Toronto and Georgian Bay.

Lake Simcoe is in its winter rhythm: slow, deep and around the brightest hours. Today brings clear skies, wind NNW around 43 km/h, rising pressure near 1010 hPa and a high of 8 °C. Water sits around 4 °C for the season (estimated). With the new moon, the solunar majors run 11:42 PM-1:42 AM and 11:18 AM-1:18 PM: the windows to build the day around.

Size and bag limits, closed seasons and protected areas are set by Ontario MNR and, in salt water and for salmon, by Fisheries and Oceans Canada, and change: confirm the current rules on the agency page linked from the Ontario licence page before you keep anything. The zone-by-zone seasons and limits are on Ontario fishing seasons.

Lake Simcoe is a lake in Ontario, Canada, covered from the Ontario reports and listed in all Canada waters.
Lake Simcoe is the big lake between Toronto and Georgian Bay, with Barrie at the head of Kempenfelt Bay, Orillia at the north end where it drains into Lake Couchiching, and Beaverton, Keswick and Innisfil on its other shores. It is fished in two seasons: through the ice for lake trout, lake whitefish and yellow perch, and in open water for bass and perch. There is no live public level gauge for the lake, so the report on this page is built from the weather and the season.
Lake Simcoe is in Fisheries Management Zone 16, with its own exceptions in the Ontario summary. Lake trout, lake whitefish and lake herring are open from 1 January to 15 March and again from the second Saturday in May to 30 September, which ends the trout and whitefish ice season in mid-March. Muskellunge are closed all year on the lake, and in Ontario it is illegal to fish for a closed species even to release it. Bass open on the fourth Saturday in June, and yellow perch are open all year.
Cook Bay at the south end is shallow perch water, Kempenfelt Bay off Barrie drops into deep water where lake trout and whitefish are jigged, and the open main basin is fished by those equipped to travel on it. In summer, look for smallmouth on rocky shoals and for perch and largemouth along the weed edges. Two tributaries, the Beaver River at Beaverton and the Pefferlaw River, are sanctuaries from 1 March to the Friday before the second Saturday in May.
Ontario’s stocking record lists more than 100,000 lake whitefish fingerlings released in Lake Simcoe every year from 2016 to 2025. The record shows the year and life stage of each release, not the day, and fingerlings take years to reach a size anglers keep.
No agency measures or certifies the ice on Lake Simcoe. Pressure ridges open and close, and people go through it most winters, so check the ice yourself or go with an operator who does. In Zone 16, ice huts must be registered online and removed before 16 March; a small fabric tent of 7 square metres or less does not need registering, and a hut left on after break-up is an offence under the Public Lands Act.
Without a live level, the page shows a seasonal water temperature estimate, labelled as one: near freezing under the ice and warming quickly after ice-out. Barometric pressure and cloud cover drive the score; perch anglers often watch for a falling barometer ahead of a winter front.
An Outdoors Card and an Ontario sport or conservation fishing licence are needed from age 18 to 64 for Ontario and Canadian residents, and for all non-Canadians. The Lake Simcoe exceptions in the Zone 16 summary, linked below, list the limits for trout, whitefish, cisco and perch; our Ontario licence page has the fees.
When the ice allows. Lake trout and whitefish close on 15 March, huts must be off before 16 March, and perch stay open all year; no agency certifies the ice.
No. The Ontario summary closes muskellunge on Lake Simcoe all year, and fishing for a closed species is illegal even if you release it.
Yes, with lake whitefish: Ontario’s record shows more than 100,000 fingerlings a year from 2016 to 2025.
