We are a grassroots, volunteer organization that draws people together from Kingston to Cornwall, Ontario, in the Thousand Islands and along the shoreline of the upper St.Lawrence River, the Kaniatarowanenneh, “the majestic and magnificent river”  

TIARA is an advocacy group for the natural environment in the Thousand Islands region. We are concerned with the ecosystem of the Islands and the river itself. As a result, we build alliances with other like-minded organizations and monitor issues involving land planning and the environment.

TIARA had a significant part in the establishment of the Official Plans for the riverfront municipalities. We keep a close eye on area development to ensure that those plans are honoured.

TIARA is recognized as being prepared to take whatever legal action becomes necessary to protect an ecosystem already fragile by 150 years of development.
