The Royal Canadian Mounted Police (RCMP; French: Gendarmerie royale du Canada (GRC), "Royal Gendarmerie of Canada"; colloquially known as the Mounties, and internally as "the Force") is both a federal and a national police force of Canada. The RCMP provides law enforcement at a federal level in Canada, and also on a contract basis to the three territories, eight of Canada's provinces (the RCMP does not provide provincial or municipal policing in either Ontario or Quebec), more than 150 municipalities, 600 aboriginal communities, and three international airports.

Although the NWMP contingent at Queen Victoria's Diamond Jubilee wore the flat-brimmed Stetson, the RCMP did not adopt it until about 1904. The original primary summer headdress was the white British foreign service helmet, also known as a pith helmet. This was an impractical choice for the Canadian west, and RCMP members wore a Stetson type hat on patrol and around camp. Sam Steele is often credited with introducing the Stetson-type hat, and when he left the force to command Lord Strathcona's Horse in South Africa, his unit adopted the Stetson. During winter, members wore a Canadian military fur wedge cap or busby. In British Columbia, the hat features a black bearskin rim belt.
