What’s the best time of year for a fly-in fishing trip in Ontario?
The best time depends on what your group wants from the week. Ontario’s fly-in season opens after ice-out, which usually arrives in May and varies by lake and year, and runs into the fall, with some operators listing May through October. Spring brings walleye into the shallows, summer brings long, warm days, and fall brings colour, cool mornings and quiet lakes.
Season dates for each species are set by Fisheries Management Zone and can change from year to year, so check the current Ontario Fishing Regulations Summary for your lake. For an overview of fly-in trips, species and lodges, see our guide to Ontario fly-in fishing lodges and trips.
Spring: opening weeks and walleye in the shallows
Late May and June are the opening weeks of the fly-in year. As the ice leaves and the water warms, walleye move into shallow bays and river mouths, and many anglers look forward to this stretch all winter. Days are cool to mild, mornings can be cold, and insects become active as early summer arrives.
There’s an energy to spring that no other part of the season has. The first floatplanes of the year are lifting off the bases, the camps are opening, and the first shore lunch of the season tastes like the end of a long winter. For groups who want the excitement of opening week, spring is the trip.
Summer: long days and settled weather
July and August bring the warmest weather of the season. Red Lake’s July average high is 24.0 °C (75 °F), according to Environment and Climate Change Canada climate normals, and around the June solstice, days at Red Lake’s latitude run past 16 hours of daylight. As the water warms, many fish move to deeper water and structure, and early mornings and evenings are often the best times on the water.
Summer is the easiest season to fit around school holidays, which makes it a natural choice for family trips and first-timers. Picture a calm evening with the light lasting until late, the kids swimming off the dock, and one more cast at the weed edge before dinner.
Fall: colour, cool mornings and quiet lakes
September and early October bring cooler days, fall colour along the shorelines and quieter lakes as the season winds down. Fish feed ahead of winter, and late-summer and fall nights bring a chance of northern lights. Check your operator’s season dates, since camps close at different times.
Picture a September week. Gold birch lines the shoreline, there’s frost on the dock in the morning, and the first boat out leaves a trail through the mist. Jackets stay on until midday, the walleye are hungry, and by evening the cabin stove feels good. On a clear night, someone steps outside and calls the rest of the group out to see the sky.
Which part of the season fits your group?
Use this chart to match your group’s priorities to the season. Conditions vary by lake and year, so ask your operator about your week.
| Your group’s priority | Spring (late May–June) | Summer (July–August) | Fall (September–early October) |
|---|---|---|---|
| Walleye in shallow water | Strong fit | Mornings and evenings | Good fit |
| Warmest weather and longest days | Cool to mild | Strong fit | Cool |
| Family trips in school holidays | Depends on school dates | Strong fit | Less likely |
| Fewer insects | Insects become active | Easing by late summer | Strong fit |
| Fall colour and northern lights | — | Northern lights possible late in summer | Strong fit |
| Quiet, end-of-season lakes | Good fit early in the season | Popular with families, so book early | Strong fit |
Booking your week
Many groups return to the same week year after year, so popular weeks at some camps fill early. Once your group agrees on a season, contact operators early and ask which weeks suit your target species. Keep travel days flexible, because floatplanes fly by sight and weather can shift flight times in any season.
Pack for the season you choose: spring and fall need warmer layers than midsummer. Our guide to what to bring on a fly-in fishing trip has a full packing checklist, and our guide to your first fly-in fishing trip walks through the journey step by step.
Find your week on the water
When you know your season, the next step is finding the lake. Explore the fly-in lodges and outposts in our guide to Ontario fly-in fishing lodges and trips, and check each operator’s season dates on its listing. Kashabowie Outposts, for example, lists a season of May through October.
