The grounds were excavated in 1979 and 1980 by the Toronto Historical Board, and again in 1982 by the Youth Committee of the Toronto Sesquicentennial Board. The outline of the original fort has been marked out in concrete around the obelisk. Two commemorative plaques — one in English, and one in French — are attached to the base of the obelisk, placed there by the Ontario Heritage Foundation. To the north, a third plaque commemorates the excavation done on the site, and to the west, a fourth plaque commemorates a visit to the site by Bertrand Delanoë, mayor of Paris, on September 6, 2003.
