The Thousand Islands Association is a not for profit organization whose main focus is the placement and maintenance of shoal markers in the 1000 Islands region of the St. Lawrence River.


TIA promotes river safety, environmental awareness & community support.

River Safety

Our 300 shoal markers are there to ensure safe navigation. In Canada our territory stretches from the Bateau Channel to Brockville, and in partnership with Save the River, from Cape Vincent to Morristown on the US side.


 We align with other oranizations that support and promote environmental awareness and preservation


On both sides of the border we provide  resources and information to the 1000 Islands Community
