Designations of national historic significance are usually commemorated with a bronze plaque installed in a location that is closely related to the designated subject and accessible to the public.
Parks Canada must receive permission from the owner of the property before installing a plaque and designated subjects are commemorated at no cost to property owners.
The plaques are inscribed with a bilingual text describing the historic significance of the subject. They are sometimes written in a third language, particularly when the commemorated subject is linked to the history of Indigenous peoples or ethnocultural communities. Following designation, the process of writing the text and producing the plaque requires an average of 18 to 24 months.
