1979 Charles Duranceau Ltee Entrepreneurs
In the shape of a maple leaf, these metal plates are stamped with the date of construction of the sidewalk and the name of the contractor that built it. Unlike other cities in Canada, such as Vancouver and Toronto, where every sidewalk is stamped with the date of its construction and the name of the contractors that built it, sidewalk stamps are rare in Montreal. This particular "find" is in bronze and is about 6 inches across.
Does your city do this?
