Recent records (2016 on) are year-only; MNRF does not publish stocking dates. Historical records (to 2015) include dates and strain.

Check the Zone 15 regulations. Some lakes have special rules; we do not summarize regs.
Guide to Eating Ontario Fish for consumption advisories.
Fish sizes are estimates: yearlings stocked 3–5 years ago are usually 30–45 cm; fingerlings take a year longer.
