When to fish muskellunge in Ontario

• Spring 3–12 ft — Post-spawn fish recover in shallow, warming bays — smaller baits, slower work.
• Summer 8–25 ft — Deep weedlines, rock points and open-water humps near bait schools.
• Fall 8–30 ft — The trophy season: big baits worked slow on steep rock and remaining green weeds.
• Winter 15–35 ft — Mostly dormant; deep basins adjacent to structure.
