Lac Ontario (Lake Ontario) stands as the easternmost of the Great Lakes and, while the smallest in surface area among them, its cool, deep waters make it one of the premier sportfishing destinations in both Ontario and New York State. Its unique geographic position means that water from all the neighboring Great Lakes flows through it before emptying into the Atlantic Ocean, creating exceptional biodiversity and supporting an extraordinary range of fish species. The lake currently holds approximately 122 different species of fish, including 12 invasive species — a dramatic increase from the 68 species documented in lake surveys during the 1970s. Whether you're trolling open water for trophy salmon and trout, working the shallower eastern basin for walleye and pike, or casting from shore in the Greater Toronto Area, Lake Ontario delivers world-class fishing opportunities across all seasons.
