How we know
- 82lakes where an angler logged one in Fish ON-Line; on 53 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.
Ontario stocks lake whitefish only in Lake Simcoe, releasing fall fingerlings to protect that lake's own genetic stock.
Inland lakes on this list run from 13 to 221,497 acres (median 2,809) and from 15 to 408 ft deep (median 106.5 ft).
When and how anglers catch lake whitefish
From 150 trip reports naming lake whitefish 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
Lake whitefish live in the Great Lakes and in deep, cold inland lakes across Ontario, north to the coastal waters of Hudson Bay. Through summer they hold deep, below the warm surface layer, feeding on invertebrates along the bottom, though in Far North lakes they also use shallower water. They are easiest to catch in winter and spring.
In late fall, as the water cools, they gather on shoals and scatter their eggs over rock and gravel; the eggs sit through the winter and hatch in spring. Fish mature at around four to seven years and can live well past 20. Some Ontario stocks are special cases: the large-bodied and small-bodied whitefish of Opeongo Lake are listed as threatened in the province.

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.
