In the Fall of 2006 a number of local anglers met to discuss their common concerns about the need for an organization to protect and enhance the ecological integrity of the aquatic habitats in Antigonish county in order to sustain a healthy fishery. Out of these discussions came the Antigonish Town and County Anglers Association which drafted a constitution in March 2007.
The organization was incorporated that year. The association is committed to promoting angling to all members of the community, developing a sustainable fisheries management program, supporting the education of anglers and encouraging young people to become involved in the sport.
The ATCAA changed its name to the Antigonish Rivers Association at the 2010 General Meeting. The association holds monthly Directors meetings from November to May. The Annual General Meeting is held the first week of March. Meetings are open and new members are always welcome.
