Dominion Police
The Dominion Police Force was the federal police force of Canada between 1868 and 1920, and was one of the predecessors of the Royal Canadian Mounted Police. It was the first federal police force in Canada, formed the year following the Canadian Confederation to enforce federal laws and perform policing duties for the Federal Government of Canada. On 1 February 1920, the Dominion Police was merged with the North-West Mounted Police to form the Royal Canadian Mounted Police as the new federal police force of Canada.
Railroad police
Canadian railways, like those of the United States, aided in nation-building and brought new police agencies into existence. Years before Confederation, railway constables were given full police powers within of company property and vehicles. The Canadian Pacific Railway initially relied on the Dominion Police, which later became the North-West Mounted Police during construction of the transcontinental railroad, but by the later 1880s were employing their own police.
