What breed of house was the Queen's Burmese?

The horses used by the Royal Canadian Mounted Police are predominantly thoroughbreds, although In March 1989, black Hanoverian broodmares and stallions were purchased to further supplement and improve our stock's bloodlines in relation to colour, substance and conformation. Hanoverians also have two predominant black lines in their breed, which benefits the bone structure and size. They are quiet by nature, almost lethargic, so crossing them with Thoroughbreds produces a well tempered horse with the desired conformation.

The RCMP breeds for colour, size, substance, and temperament. There is not a supply of black horses like the RCMP requires anywhere in the world.

The RCMP first start breeding their own horses about 1939, after Commissioner Wood's decision to use only black horses. The first breeding farm was established on a 720 acre ranch at Fort Walsh in Saskatchewan (the same site as the Mounted Police Fort built in 1875). The Farm provided horses for mounted training in Regina and Ottawa.

The R.C.M.P. Remount Ranch at Fort Walsh then started the process of raising the large black horses which have become an integral part of the R.C.M.P.'s internationally recognized image. A carefully monitored breeding program was implemented in a corral system behind the fort. Thoroughbred black stallions crossed with mare's with strains heavy horses produced the desired offspring; horses with not only size and presence, but also beauty and grace. At Fort Walsh the horses were raised to three year olds, halter broken, and branded (later tattooed). Then they were driven to Maple Creek, loaded on the train and shipped to Depot in Regina (later the horses were shipped by semi-trailer). Depot was where these young horses were trained, and where in turn they would help to train the men. Fort Walsh horses were also used in the R.C.M.P. Musical Ride. Many of the horses in the Ride today can trace their ancestry to horses raised at Fort Walsh. One mare who served in the Musical Ride, Burmese, who was born at Fort Walsh in 1962, became a favourite of the R.C.M.P. and in 1969 was given to their Honourary Commissioner; Her Majesty Queen Elizabeth II, Queen of Canada. For nearly 20 years the Queen could be seen riding Burmese on state occasions. The presentation of a horse to Her Majesty has been a tradition of the R.C.M.P. ever since.

Imagine if you could breed houses.. wow.

One horse presented to the queen, George, is half hanovarian and half thoroughbred. I found somewhere that says he has the same bloodline as Burmese, possibly saying they are the same breeds or at least similar? I don't know.

There is a breed of horse called a Canadian. Could be it was that breed. In pictures, Bu8rmese appears to have that conformation.

Could also be that Burmese was not any particular breed. Just because a horse carries a queen does not mean it has to be a part of some registry. Many police horses are chosen for their demeanor, and breed is of little consequence.
