The Old Stone Mill in Delta Ontario is a National Historic Site showcasing milling technology and 1800s industrial heritage. The mill was built in 1810 as an automatic gristmill and it is one of the finest examples of early industrial architecture in the region. It is open from 10 am to 5 pm daily from Victoria Day weekend to Labour Day. Admission is free (donations appreciated.)
The mill features many interpretive displays, an operating waterwheel, millstones, bolter, grain elevators, and artifacts illustrating the grist milling process through the years. You can tour the mill yourself or enjoy a free guided tour.
During the summer we grind heritage wheat into flour using our 200 year old millstones. Our stone ground flour is available in our gift shop which also offers interesting mementos of your visit.
