Species guide
The species that matter on Lake Simcoe: seasons written for the Canadian year, and how to fish each one. Today's ratings live in the report above.
Lake trout
Ice season, and spring after ice-off
The big char of cold, deep lakes: Lake Simcoe, the Kootenay and Shuswap systems, the northern lakes. A winter favourite through the ice, where the season allows. Fish come shallower after the lake turns over; cast or troll the shoals.
Lake whitefish
The ice season
A cold-water schooling fish taken mostly through the ice, notably on Lake Simcoe. Soft mouth, subtle bite. Fish come shallower as the lake cools; small jigs near the bottom.
Yellow perch
Year-round; the ice season at Lake Simcoe and Long Point
The ice-fishing fish of Lake Simcoe, Long Point Bay and Lake St. Clair, and a summer staple on every Great Lakes shore. Schools move constantly. Schools tighten on the deeper flats; bait near the bottom.
Smallmouth bass
Opens late June in most of Ontario; best July to October
The rock-and-current bass of the Great Lakes shores, the Bay of Quinte, the St. Lawrence and Lake St. Clair. The Ontario bass season opens in late June in most zones, after the nesting period. Fall schools on the deeper rock: jerkbaits and hair jigs.
Northern pike (jackfish)
Spring, fall and the ice
Called jackfish on the prairies. Found in almost every lake and slow river from Ontario to Alberta; big fish in the cold, deep lakes. The fall feed: big swimbaits and spoons in the shallows where the baitfish gather.

About this water
Lake Simcoe is a lake in Ontario, Canada, covered from the Ontario reports and listed in all Canada waters.
Fishing Lake Simcoe: the full guide
Lake Simcoe
Lake Simcoe is the big lake between Toronto and Georgian Bay, about an hour north of the city, ringed by Barrie on Kempenfelt Bay, Orillia, Beaverton, Keswick and Innisfil, and it is the most searched ice-fishing lake in Canada. In winter, hut villages spread across the ice from Cook’s Bay to Kempenfelt Bay; in summer, the same water fishes for bass and perch. There is no live public level gauge for the lake; the report on this page is built from the weather and the season.
Species and seasons
Yellow perch, lake trout and lake whitefish are the winter fish, taken through the ice in the deeper water for trout and whitefish and on the shallower flats for perch; smallmouth and largemouth bass open in summer, and northern pike and muskellunge are present. Lake Simcoe sits in its own fisheries management zone, with seasons and limits for trout, whitefish and bass set out in the Ontario regulations summary.
Where to fish it
Cook’s Bay at the south end is the perch and ice-hut area, Kempenfelt Bay off Barrie holds deep water for lake trout and whitefish, and the main lake between Beaverton and Georgina Island is fished by those with the gear to travel. In summer, bass are fished on the rocky shoals and weed edges around the shoreline.
Planning a visit
Ice-hut operators rent heated huts by the day around the lake when the ice allows, and the marinas and launches serve summer boats. The lake is big and exposed; wind can build waves quickly in summer and push ice around in winter.
Ice and safety
No agency measures the ice on Lake Simcoe for anglers. The ice forms unevenly, pressure ridges open and close, and people go through it most winters. Check the ice yourself or go with an operator who does, stay off it early and late in the season, and follow the local police and conservation authority warnings.
Reading this report here
Without a live level, the page shows the seasonal water temperature estimate, labelled as one: near freezing under the ice, rising fast in spring. Pressure and sky build the score, and a falling barometer before a winter front is a classic perch bite.
Licence, access and rules
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 zone’s seasons and limits are in the regulations summary linked below. Our Ontario licence page has the fees.
