About this water

The Credit is the GTA's home river — a productive Lake Ontario tributary with strong spring and fall steelhead, autumn chinook and coho, and resident/stocked brown trout up at the Forks of the Credit. It's genuinely good fly fishing within reach of downtown Toronto: lake-run rainbows on eggs and nymphs in the lower river, and cooler resident-trout water above.

Under the surface

The Credit is the Greater Toronto Area's home steelhead river — a Lake Ontario tributary with strong spring and fall lake-run rainbows, autumn chinook and coho, and resident and stocked brown trout in its cooler upper reaches (the Forks of the Credit). Remarkably productive given its urban setting, it offers genuine fly fishing for lake-run and resident trout close to the city.

Wading: Flashy urban flows, slick clay, warm lower river in summer

  • Limestone
  • Partly confined
  • Pool riffle
  • Medium river
Conservation note

Naturalised lake-run steelhead, chinook and coho, plus resident/stocked brown trout in the cooler upper reaches (retention provincially regulated). Sanctuary reaches protect spawners. Clean-Drain-Dry.
