Of the game fish government surveys recorded in this lake, lake trout, northern pike, pumpkinseed and yellow perch are open at least part of the winter under the zone-wide rules.

S = sport fishing licence, C = conservation licence (daily catch and possession). Dates are worked out for 2026–27 from the wording of the 2026 summary. Ontario publishes a new summary every January 1, so check the 2027 edition for dates after December 31.

Constance Lake is not listed by name in the zone's species or waterbody exceptions or fish sanctuaries. Some exceptions cover whole townships or river systems, so read the zone page before you go.

Ice huts in Zone 10

Huts must be registered (free, once) and show the number outside; fabric shelters under 7 m² are exempt. Remove your hut by March 31, and in any case before the ice breaks up. You may fish with two lines through the ice in most waters, within 60 m and in sight of each.
