Provincially Designated Heritage Properties and Plaque Locations What is a Heritage Plaque? The Heritage Plaque program is administered by the Township's Heritage Committee. A plaque is voluntary and does not put any restrictions on future activity on the property such as building alterations. For more information about our Plaque Program, click here. What is a Provincially Designated Heritage Property? Municipalities may pass bylaws to formally designate properties of cultural heritage, value or interest under the Ontario Heritage Act. Formal designation of heritage properties is one way of publicly acknowledging a property’s heritage value to a community, however that formal designation could restrict future modifications/improvements to the property. This process is laid out in this Heritage Tool Kit Guide: http://www.mtc.gov.on.ca/en/publications/Heritage_Tool_Kit_DHP_Eng.pdf Provincially Designated Properties in Guelph/Eramosa The map below identifies the properties in Guelph/Eramosa that currently have Provincial desginations.
