The Muskoka Lakes Association was organized in 1894 by a group of summer cottagers, and since then has worked on behalf of permanent or part-time residents of Lakes Muskoka, Rosseau and Joseph. "The Association was established to unite all those interested in the lakes and their vicinities in order to protect and promote the interests of property owners, cottagers and tourists, preserve the safe, healthful and sanitary condition and scenic beauty of the lakes; and to encourage skill and prudence in aquatic sports ... Association members were instrumental in forming the Muskoka Lakes Golf and Country Club, which is the scene of the annual regattas and other Association-sponsored activities. The Association has had a major influence on the history of the lakes since the beginning of the century."
Issues of interest to the Association since its beginnings have always included both political and environmental concerns: roads and other transportation facilities serving the area, sanitation standards, well-marked waters, fishing, fire and police services, taxation, water and air quality, acid rain, boating safety, and any other factors contributing to the health, security and pleasure of those living in and around the lakes.
