We are an international association responsible for shoal marking and promoting river safety, environmental awareness and community in the 1000 Islands region of the St. Lawrence River.

Why does TIA need your membership?

Each year TIA places and maintains over 300 shoal markers throughout 1864 islands in both Canadian and American waters. This is TIA’s flagship program and cannot be sustained without membership support – TIA receives no government funding . It is an expensive service but one fully warranted by lives saved and accidents prevented.

TIA’s most important asset is you, our members. Help support TIA’s Mission to promote river safety, environmental awareness and community

Just think what the river would be without shoal markers

The Coast Guard provides channel markers for primary river navigation only. However, beyond these charted routes the river is a dangerous place for boaters without TIA’s shoal markers.

There is a cost to place the markers in the spring, remove them in the fall, and maintain and purchase new markers destroyed by age and weather. 

TIA needs to increase its current membership by significant numbers to fully fund the escalating costs of its shoal marking program and to initiate environmental awareness objectives.
