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.

At the First Parliament of Upper Canada in Niagara-on-the-Lake on September 17, 1792, provision was made for the formation of a "police system." Initially, policing jurisdictions were limited to districts, townships, and parishes. In 1845, a Mounted Police Force was created in order to keep the peace in areas surrounding the construction of public works. It became the Ontario Mounted Police Force after Canadian Confederation.
