The TIA provides and places shoal markers, nearly 200 starting mid-way on the Bateau Channel, north of Howe Island all the way down river to Brockville/ Morristown on most boating channels from Lake Ontario to Brockville. The TIA has also placed fire pumps and life-saving defibrillators in the region. The TIA celebrates the river, the ecology and the natural biosphere that surrounds us by offering scholarships each year to worthy high school students in Canada and the US.
Most of the work is done by volunteers except for the placement of the 200 ROCK and SHOAL markers. All expenses are covered by dues, grants and donations.
