Old Stone Mill NHS - The Delta Mill Society

We're opening for the 2022 season after two years of COVID closure. Please join us at 11 am on Saturday May 21 to help celebrate the public re-opening of our 212 year-old mill. There will be cake! Milling starts at 1 pm. See you there!

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. Our stone ground flour is available in our small Mill Shop which also offers interesting mementos of your visit.


As we move into our open season for 2022, we are searching for volunteers to lend a hand at the Old Stone Mill.

What we urgently need are helpers who can give us 3 hours as a "Meet and Greet" person in the Mill Gift Shop. There is no need to provide tours of the Mill, just provide a warm and welcoming greeting to our visitors and give them the 'Self Guided Mill Tour' brochure to allow them to do their own tours.

Can you find some time in your schedule over this period to be a much valued and highly appreciated Mill 'Meet and Greeter'? A morning or afternoon shift? What day(s) of the week work for you? Which suits you best?? Let's figure it out!...because if we do not get enough volunteer help we will not be able to open our doors until July.

Please email volunteers.tdms@gmail.com to let us know by May 20th if you can help or if you have any questions.

History of the Old Stone Mill

The Old Stone Mill is the only surviving pre-1812 stone grist mill in Ontario. Built in 1810, it followed the design of an automatic flour mill created by American inventor Oliver Evans. It has some unique features, including having acted as its own dam. You can learn all about the history of the mill by visiting our History Page (and by visiting the mill to actually see and touch history)


The Old Stone Mill and the Old Town Hall are owned and operated by The Delta Mill Society, a self-funded, non-profit organization run by volunteers. Accordingly, we have lots of people to thank for helping us get to where we are today. See our Thanks Page for full details.
