All memberships in TIA are tax deductible!!

Did you know that TIA is the sole organization responsible for the spring placement, seasonal maintenance and fall removal of nearly 200 orange and white ROCK markers  between the eastern tip of Howe Island and Brockville?

Contrary to what many still believe, this work is done by TIA, NOT Parks Canada or the Canadian Coast Guard.

Beyond this, TIA also provides the funding for an additional 100 markers that are placed in American waters each season by Save The River between Cape Vincent and Morristown.

Established in 1934, TIA is a not-for-profit organization that relies heavily on membership to fund
the work we do each summer.
