Northern pike (jackfish) in Canada

Called jackfish on the prairies. Found in almost every lake and slow river from Ontario to Alberta; big fish in the cold, deep lakes. Spring, fall and the ice. Best month across the Canada waters we cover: May.

Identification and biology

The northern pike, also called jackfish, is a long, slender predator with a broad, flattened snout full of teeth, green to olive-brown on the back with rows of yellow to whitish bean-shaped spots on the sides. Fisheries and Oceans Canada gives its range as the rivers and lakes of Quebec, Ontario, the Prairie provinces, the northeast corner of British Columbia and the three territories, and tells it from the muskellunge by its pale spots and the rounded tips of its tail. Pike spawn in spring immediately after the ice melts, scattering their eggs over flooded vegetation in areas that may be dry the rest of the year. A pike lurks at the edge of the weed beds and takes whatever is readily available, from fish and crayfish to frogs and young waterfowl.

Where they live through the year

In spring, pike are in the shallow bays and marshes; in summer, the smaller fish stay in the weeds and the big ones move to deeper, cooler water; in fall they feed heavily in the shallows where the baitfish gather; under the ice they cruise the weed edges and the shallow bays.

The mistakes that cost fish

Fishing without a wire or heavy fluorocarbon leader, and losing fish and lures to the teeth. Handling pike without long pliers and care: the gill rakers and teeth cut, and fish to be released should be handled quickly. Fishing the shallows for big pike in the heat of summer. Retrieving too fast in cold water is another: in spring and late fall, pike often follow a lure and turn away if it does not pause.

Reading the report for pike

Pike bite in almost any weather, but a change in pressure and a windy day often trigger the bigger fish. In winter, the ice is fished with tip-ups where it is safe. Cloudy, breezy days are often the best.

Where to fish them in Canada

On this site, pike are on the pages for Lake of the Woods, Lake Winnipeg, the Red River at Selkirk, Lake Diefenbaker, Tobin Lake, Pigeon and Sylvan lakes, Lake Simcoe, Rice Lake, Lake St. Clair, the Bay of Quinte, the St. Lawrence and the Detroit River. The Diefenbaker, Tobin, Pigeon, Sylvan, Lake of the Woods, Lake Winnipeg and Red River pages carry live Water Survey of Canada gauges, and every page says that no agency certifies the ice for anglers. Manitoba’s anglers’ guide lists the fish as northern pike (jackfish), a reminder that both names mean the same fish at the licence counter.

Playbook by water temperature

The plan the daily report picks for northern pike (jackfish) in each band; the water temperature on each page is a seasonal estimate for its type of water and says so.

Hot water (over 27 °C)

Big pike go deep and cool; small ones stay in the weeds. Spoons and spinnerbaits along the deep weed edges.

Warm water (18 to 27 °C)

Spinnerbaits, spoons and jerkbaits over the weed beds and along the points.

Cool water (10 to 18 °C)

The fall feed: big swimbaits and spoons in the shallows where the baitfish gather.

Cold water (under 10 °C)

Under the ice where it is safe: tip-ups with dead bait in the shallow bays.

Common questions

Is a jackfish a pike?

Yes, jackfish is one of the common names Fisheries and Oceans Canada lists for the northern pike, and Manitoba’s guide uses it too.

Do I need a wire leader for pike?

A wire or heavy fluorocarbon leader prevents bite-offs from the teeth.

When is the best time for big pike?

Spring after ice-out and fall, when big fish are in the shallows.
