Ice Fishing in Ontario
Safety, species, gear and where to fish through the hardwater season.
From first ice on the back bays to late-season lake trout, everything you need to fish Ontario's winter safely.
Ontario's Hardwater Season
Ontario's ice fishing runs from first-ice in December through late-season lake trout in March, with fisheries as varied as Lake Simcoe perch, Nipissing walleye, Bay of Quinte walleye and pike, and Shield-lake whitefish. It's some of the best fishing of the year — but the margin for error is smaller than open water. Start with safety, stay mobile, and match your presentation to cold, sluggish fish.

Ice Fishing Gear Checklist
- Ice picks worn around the neck for self-rescue
- Spud bar or auger to test ice as you go
- Cleats or ice creepers to reduce falls
- Insulated, waterproof boots rated well below freezing
- Layered clothing with a windproof outer shell
- Floater suit or float jacket in early- and late-ice windows
- Shorter, sensitive ice rod plus tungsten jigs & small spoons
- Flasher / ice sonar to stay mobile and find fish faster
- Portable shelter for wind protection on big lakes
- Fully charged phone in a waterproof case (VHF if you have one)
Always check local ice conditions with a bait shop, outfitter, or club before heading out. Ice thickness varies across a single lake — around inlets, narrows, pressure ridges, and current — even when the rest of the surface looks solid.
