Use and Protocol
The Queen's personal Canadian flag is employed only when the Queen is in Canada or is attending an event abroad as the Canadian head of state; for example, the flag was unfurled at Juno Beach in France when the Queen was present there for commemorations of the Normandy Landings. The flag must be broken immediately upon the sovereign's arrival and lowered directly after her departure from any building, ship, aircraft, or other space or vehicle. On land, as per Department of National Defence protocol, the Queen's standard must be flown from a flagpole bearing as a pike head the crest of the Canadian royal arms. As the monarch is the personification of the Canadian state, her banner also takes precedence above all other flags in Canada, including the national flag and those of the other members of the Canadian Royal Family, and is never flown at half-mast.
No other person may use the flag; the Queen's federal representative, the governor general, possesses a unique personal flag, as does each of the monarch's provincial viceroys. Flags are kept at the Queen's Canadian residence, Rideau Hall, and supplied to Department of Canadian Heritage royal visit staff by the household staff prior to the Queen's arrival.
Protocol is sometimes, though rarely, officially broken. On 9 August 1902, the day of the coronation of King Edward VII, the monarch's royal standard (then the same in Canada as in the United Kingdom) was raised on a temporary flag pole at His Majesty's Dockyard in Halifax, Nova Scotia. Similarly, for the coronation of Queen Elizabeth II on 2 June 1953, the sovereign's royal standard was broken atop the Peace Tower on Parliament Hill in Ottawa. Sixty years later, on 6 February 2012, the Queen's personal standard for Canada was unfurled at her Ottawa residence, Rideau Hall, and on Parliament Hill, as well as at other legislatures across the country to mark the monarch's diamond anniversary of her accession to the throne; permission to do so was granted by the Queen.
