Thessalon is a town in the Canadian province of Ontario, located at the junction of Highway 17 and Highway 129, surrounded by but not part of the municipality of Huron Shores, and part of the District of Algoma.
Thessalon sits on the north shore of Lake Huron in the Algoma District. The main industries are timber and tourism. The population of Thessalon was 1,312 in the Canada 2006 Census. The town is a popular retirement community. There's an arena and one grade school in the town. It's home to a few local celebrities, including Jackie Layer (former assistant coach of the Colorado Rockies), and Lloyd Boyer (former Montreal Canadiens prospect/small town hockey legend). William Tremblay of the Sault Greyhounds was born here, and Angelina Napolitano, the first person in Canada to use the battered woman defence for murder, lived here briefly in the early 20th century. It was also home to the Thessalon Flyers.
The Thessalon River runs off the mouth of Lake Huron at Water Street, and runs through the town. Fishing is excellent in the high-tide river, with game from yellow perch, pickerel, bass, northwater salmon, muskie and Jellyfish.
