Lake trout are the giants of Canadian coldwater — the largest trout in the country, reaching 40+ pounds in big northern lakes. They're deep-water predators that require cold, oxygen-rich water, and they're a prized catch across the Shield country and northern lakes.
Forked tail (like a salmon). Dark green to grey body with light cream to yellow vermiculations (worm-like markings) — not spots.White leading edges on all fins with black lines behind them. Large mouth with strong teeth. Head and body are elongated and streamlined for deep-water cruising.
Lake trout require cold (8–12°C / 46–54°F), deep, oxygen-rich water. They're found in deep clear lakes across the Canadian Shield, particularly in ON, MB, SK, and northern waters. In summer they hold at the thermocline (40–80+ ft); in spring and fall they come shallower (15–40 ft) and can be caught trolling or casting.
Lake Trout can be found across these provinces and territories:

Matching your bait to the conditions is one of the biggest factors in catching Lake Trout. Here's what works when:
| Weather / Condition | Best Bait & Lures | Technique |
|---|---|---|
| 🌸 Spring (cold water, shallow) | Large spoons (Len Thompson, Williams), minnow-imitating crankbaits | Lake trout come shallow (10–30 ft) in spring after ice-out. Troll or cast over rocky points and shoals. |
| ☀️ Summer (deep) | Downriggers with spoons (Dimple, Sniper), wire line with heavy spoons | Trout go deep (50–100+ ft) in summer. Downriggers are essential to get baits down to the thermocline. |
| 🍂 Fall (cooling water) | Large spoons, big crankbaits, jigging spoons over deep structure | Trout move shallower as water cools — casting and vertical jigging over humps and points is effective. |
| 🧊 Ice fishing | White tube jigs (3–5 inch), airplane jigs, smelt or cisco dead-sticked on bottom | Jig aggressively to call fish in, then deadstick a bait nearby. Use heavy line (15–25 lb) for big fish. |
| 🌬️ Windy / Overcast | Large spinners, jerkbaits, big spoons | Trout are more active in lower light and wind — troll shallower and faster than in calm/bright conditions. |
Spring (May–June): lakers come shallow post-ice — some of the best fishing of the year. Summer (July–August): fish go deep — downriggers required. Fall (September–October): cooling water brings them shallow again, and they're feeding heavily. Ice (January–March): active jigging in 40–80 ft over structure.
