Community info

In the furthest reaches of Eastern Ontario, you’ll find Cornwall and SDG Counties. From the mid-sized city of Cornwall to the most picturesque villages like Williamsburg in the west and Williamstown in the east, there’s a timeless appeal here. Picture this: heritage buildings peppering the landscape, wondrous waterways that beckon boats, fishing rods and swimsuits, with endless swaths of forests to explore on foot, bike, snowshoes and skis.

All this serves as a 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!

To learn more about all there is to see and do here, explore these Doors Open sites or visit Cornwall Tourism and SDG Tourism.
