SOUTH GLENGARRY, Ontario – The Raisin Region Conservation Authority (RRCA) announced that it was terminating its relationship with the Cooper Marsh Conservators (CMC). The CMC are a volunteer organization that has assisted in the operation of the Cooper Marsh Conservation area, which is owned and operated by the RRCA. At issue, is the CMC’s advocacy against a proposed development of land adjacent to Cooper Marsh. Run Guo Investments Canada Ltd./Fotenn Planning + Design petitioned the Township of South Glengarry to rezone land that they own just east of Cooper Marsh to allow for the development of 25 camping sites.
