For more than two centuries, the Williamstown Fair has been the gathering place for thousands of area residents of our rural community, as well as many visitors from afar. Majestic pine trees, manicured lawns and beautiful well maintained heritage style buildings provide the ideal setting for “Canada’s Oldest Annual Fair”

The St. Lawrence Valley Agricultural Society takes great pride in presenting a Fair which is well recognized as a “Heritage Fair with a family friendly atmosphere” with exhibits, programs, competitions and entertainment representing the rural agricultural way of life.

While much has changed over the years with families becoming busier, the one thing that has not changed is the commitment of the rural community to assist the Board of Directors of the Society to ensure the continuation of this historic Fair and annual gathering of families and friends. There are concessions, dinners in the meeting place on Saturday & Sunday and a Free Corn Roast, 6:30 PM on Saturday.
