For over 80 years, TIA has played a key role with more than 4 generations of river families.


The Thousand Islands Association (TIA) is a Charitable, Non-Profit International Association. We place river shoal markers and are proactive in addressing membership concerns about river safety and environmental awareness in the 1000 Islands region of the St. Lawrence River.

Our Community is families who are boaters, property owners, visitors, local government, local business and service providers who share the river and the benefits of a safe and beautiful environment.
