In the farthest reaches of Eastern Ontario, you’ll find Cornwall and SDG Counties. From the mid-sized city of Cornwall to the most picturesque villages — such as Williamsburg in the west and Williamstown in the east — there is a timeless appeal here.

From heritage buildings peppering the landscape and wondrous waterways that beckon boats, fishing rods and swimsuits, to endless swaths of forests to explore on foot, bike, snowshoes and skis — these all serve as the beautiful, year-round backdrop for amenities, activities and adventures. Discover restaurants, wineries, breweries, beaches, boutiques, bass tournaments, bed-and-breakfasts and accommodations, music and theatre venues, cyclotourism routes, county fairs, lavender-picking farms, campgrounds . . . and more!
