The cathedral houses a remarkable collection of altar frontals, all restored in 2001 by parishioners under the supervision of the Quebec Conservation Centre. The most famous, a gift from King George III in 1761, is now too delicate for use. Traditionally, Westminster Abbey's coronation draperies were repurposed into altar frontals for key Anglican sites, as seen in the blue and gold fabric from George VI’s coronation, a portion of which is displayed here. Another notable piece is a white, blue, and gold frontal crafted by the Sisters of Saint John the Divine in Toronto, gifted in 1904 for the cathedral’s centennial.
