The City of Ontario's first survey of historic properties took place in 1983. The Survey identified almost 3000 properties as being eligible to be designated Historic Landmarks or as part of Historic Districts. Of the almost 3,000 on the list, approximately 300 properties were nominated for designation. Currently, Ontario has designated over 90 properties as Local Historic Landmarks and 7 Historic Districts.
