History of the Old Stone Mill

The Old Stone Mill in Delta, built in 1810-11 by William Jones and Ira Schofield, is one of the earliest surviving, fully automatic, grist mills of Upper Canada. In 1817 the mill was described as "unquestionably the best building of the kind in Upper Canada".

In 1963 the last owner of the Mill, Hastings Steele, deeded the Old Stone Mill to a group of four people in trust, for the sum of one dollar. Mr. Steele's prime concern was that the Mill should be preserved and would in time become a museum of milling technology. These four people founded the The Delta Mill Society later the same year and in 1972 the Society was incorporated as a Non-profit Corporation in the Province of Ontario.

The Historic Sites and Monuments Board of Canada declared the Old Stone Mill at Delta to be a National Historic Site in 1970 and it is the only surviving pre-1812 stone grist mill in Ontario. In 1978 the Old Stone Mill was designated under the Ontario Heritage Act.
