[1] It was designated as a National Historic Site in 1995[2] and is one of only three Chapels Royal in Canada, elevated by Queen Elizabeth II in 2004.

While not housed in the chapel, on special occasions, a silver Communion set given by Queen Anne in 1711 as a symbol of the alliance between the Crown and the Mohawks, is displayed and used.

A communion chalice was given by Elizabeth II in 1984 to mark the bicentennial of the coming of the United Empire Loyalists, including the Mohawks, to Ontario.

A Roman Catholic group associated with the Personal Ordinariate of the Chair of Saint Peter celebrates there regularly, at the invitation of the Mohawk leadership.

The style, popular in the mid 19th century, is demonstrated in the narrow lancet windows and dripstones, stepped piers on the tower and flanks of the nave, and crenellations and pinnacles on the spire, all contributing to an overall sense of verticality common to gothic architecture.
