Police
In Canada, the Royal Newfoundland Constabulary was founded in 1729, making it the first police force in present-day Canada. It was followed in 1834 by the Toronto Police, and in 1838 by police forces in Montreal and Quebec City. A national force, the Dominion Police, was founded in 1868. Initially the Dominion Police provided security for parliament, but its responsibilities quickly grew. The famous Royal Northwest Mounted Police was founded in 1873.
The merger of these two police forces in 1920 formed the world-famous Royal Canadian Mounted Police.
Metropolitan Police Mounted Branch
The Metropolitan Police Mounted Branch is the oldest part of the Metropolitan Police, having been formed in 1760 (some 38 years prior to the Thames Marine Police Force and 69 years prior to the formation of the Metropolitan Police) as the Bow Street Horse Patrol. The primary purpose of the Bow Street Horse Patrol was to patrol the turnpikes approaching London.
