The iconic black and white Oakville Historical Society plaques that you see on properties around town have been provided by the Oakville Historical Society since the 1950s. 

The plaques typically include the date of construction of the property, the name of the original (or early) owner or tenant, and his or her occupation.

Any owner of a historical property may order an Oakville Historical Society black and white plaque whether or not the property is designated or listed as a property of interest. The purpose of the OHS plaque is to show pride in ownership and provide a bit of history of the building. Initially, properties had to be at least 100 years old to qualify but plaques are now available for homes of lesser age.
