One of the longest running agricultural fairs in Ontario, The Delta Fair is a summertime highlight for the area for generations. The Delta Agricultural Society is celebrating 195 years of the fair in 2025! Enjoy fun for the whole family with children’s shows, a midway, games, truck pull, horse and animal shows, lawn mower races, live entertainment, homecraft exhibits, chainsaw carving and much more. 

The Delta Fair is a village-wide celebration of the fall harvest. Vendors line the main street and craft vendors can be found at the Fairgrounds along with live music and a car show. The Old Stone Mill is open for tours with a milling demonstration in the afternoon.  Blacksmithing demonstrations are a favourite for visitors in the blacksmith shop beside the Old Stone Mill, National Historic Site. The Old Town Hall is home to the Ginormous Book Sale and the Friends of the Mill table featuring a variety of home baking, preserves, vegetable produce, crafts, plants, dried flowers, all donated to raise funds for the heritage Mill.  Lots of food, fresh-baked goodies, and cool stuff for sale.

Visitors from Ottawa, Kingston, Brockville and across Ontario to enjoy the small village atmosphere of Delta.
