Home District School
On this site, on June 1, 1807, The Rev. George Okill Stuart opened the first public school at York in a small one-storey stone building attached to his modest frame house. In 1813 the school was removed to a barn at the corner of King and Yonge Streets where classes were held until 1816 when the "Old Blue School" was erected on Church Street.
