Each of the Trust's commemorative plaque programs has a specific plaque and purpose. The Provincial Plaque Program is an adjudicated program that uses distinctive blue and gold plaques to commemorate and interpret significant people, places and events in Ontario's history. These stories always have a broader provincial significance. In addition to provincial plaques, the Trust also supports communities through local markers to commemorate people, places and events that have more of a community focus. Both the Provincial Plaque and Local Marker programs accept applications from the public. The Premiers' Gravesites Program, however, is specific to the burial places of Ontario's premiers. The purpose of the Premiers' Gravesites Program is to honour Ontario's premiers and their service to Ontario by marking their gravesites. Specially designed bronze markers will be inscribed with the individual premier's name and dates of service.

Eighteen premiers will be commemorated through this marker program, starting in November 2008. The program will be implemented over five years. The first to be commemorated will be The Honourable John Sandfield Macdonald (who served as premier from 1867-71), in St. Andrews, near Cornwall.

The program will be implemented over five years. The Trust will work with cemeteries or cemetery boards, communities and descendants, where possible, to determine a suitable date for each event. For more information about upcoming events …

Fourteen of the 18 deceased premiers have had provincial plaques unveiled to honour them. These plaques are located at sites related to a premier's original riding and/or place of birth. Locations include: municipal parks, residences, museums, schools, county courthouses and churches.

The intent of the program is to commemorate each premier's gravesite with a bronze marker and the Ontario flag, in accordance with the rules of the individual cemeteries and archaeologists.
