- 66lakes where an angler logged one in Fish ON-Line; on 48 of them a single trip, one angler’s report
Self-reported by anglers, not a Ministry survey. A lake that isn’t listed may still have them: a lake appears here only once an angler has logged this fish there.
Inland lakes on this list run from 7 to 221,497 acres (median 707) and from 5 to 230 ft deep (median 46 ft).

Life in an Ontario lake
Channel catfish are the largest catfish in Canada. In Ontario they are common in the south, including Lake Huron, Georgian Bay, Lake Simcoe, Lake St. Clair, Lake Erie and Lake Ontario, and in large rivers such as the French, Ottawa and upper St. Lawrence; they also occur in the northwest. They favour deep holes over sand, gravel or rock, often in current below dams and riffles, and feed by day and at night.
Spawning runs from late spring into summer, often after a move into rivers, with eggs laid in sheltered spots such as undercut banks, logs or rock piles and hatching in about a week. Growth in Ontario is slow and the fish are long-lived: ages of up to 40 years have been reported.

Rules and eating
Before fishing, check the current Ontario Fishing Regulations Summary for your Fisheries Management Zone, any exceptions for the waterbody, and your licence type. Angler catch reports show what people logged, not what is legal to catch or keep. Fish ON-Line itself (how to use it) maps the zones and exceptions. Before eating fish from a particular lake, check the Guide to Eating Ontario Fish.
