About this water

The Humber is one of Toronto's accessible migratory rivers — lake-run steelhead in spring and fall, big autumn Chinook and coho, and brown trout in the cooler upper watershed, all within the city. Nymph eggs and stoneflies for the steelhead on the clarity drop; mind the crowds and the sanctuary rules on this urban water.

Under the surface

A major Toronto Lake Ontario tributary running through the city to the lake — lake-run steelhead and autumn Chinook/coho, with resident and stocked brown trout in the cooler upper reaches. Urban/suburban water that concentrates migratory fish in spring and fall.

Wading: Urban flows, slick clay, crowds at the runs

  • Glacial till
  • Partly confined
  • Pool riffle
  • Medium river
Conservation note

Naturalised lake-run steelhead, Chinook and coho, with resident/stocked brown trout upstream (retention provincially regulated). Sanctuary reaches protect spawners. Clean-Drain-Dry.
