How we know
- 154lakes where an angler logged one in Fish ON-Line; on 89 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 526) and from 5 to 300 ft deep (median 50 ft).
When and how anglers catch bluegill
From 345 trip reports naming bluegill on the lakes above, logged by anglers in Ontario’s Fish ON-Line app. These are self-reported trips, not a Ministry survey: they show when and how people fish for them, not how many fish a lake holds.

Life in an Ontario lake
Bluegill prefer warm lakes and ponds and shallow, weedy bays of larger lakes, in fairly clear water. They are plentiful in many southern Ontario waters, including the lower Great Lakes, the Kawarthas and the Rideau Lakes, and also occur in some waters of central and northwestern Ontario such as Quetico Provincial Park. They tolerate warm water and low oxygen and often travel in schools.
Bluegill spawn later than pumpkinseed, usually by two to three weeks, with activity peaking in early July. Males clear nests down to hard bottom in shallow water and guard the eggs and young for one to two weeks. Growth is quick at first and then slows: a 17.5 cm (7 in) fish may be about six years old and a 22.5 cm (9 in) fish ten or older.

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.
