TIA’s most important asset is you, our members. Without your membership support, TIA would not be able to continue its programs and activities throughout the year. Most importantly, your membership fees combined with donations provide the funds necessary to maintain what many believe to be the most important safety program on the river, our shoal marking program.

Please take a moment to join or renew your membership. Simply click on the appropriate membership category below. Thank you for your support.

Why Your Membership Matters

Each year more than 300 shoal markers are placed throughout the 1864 Islands. TIA is responsible for placement in Canadian waters and in partnership with Save the River for placement in American waters. Think how dangerous the river would be if there were no shoal markers. For the safety of all of us, our family, friends and visitors who boat in the Thousand Island region, please be a TIA member and supporter.
