Commemorative plaques are useful cultural artifacts because they give us, the visitors, a sense of the importance of a place, tying us to that location in both the present and the past. This is why people create them, often at great expense, and erect them in public view.
Heritage Toronto values the proud history of Canada's largest city. Its commemorative plaques can be found throughout the city. The creation and establishment of a commemorative plaque is itself a notable event, so this particular plaque commemorates itself, which was unveiled to the public on October 10, 2018--a date of great historical importance. It is, to the best of my knowledge, the only recursive commemorative plaque in Toronto.
