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 and is one of the finest examples of early industrial architecture in the region.

The mill features 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. Adjacent to the mill is our newly restored Blacksmith Shop which is open during special events.

Notes from "How it’s Made"

Built in 1810, this is one of the earliest surviving grist mills of Upper Canada. In summer months, heritage wheat is ground into flour using these 200 year old millstones.
