The Yukon Field Force, later termed the Yukon Garrison, was a unit of 203 officers and men from the Permanent Force of the Canadian Militia that served in the Yukon between 1898 and 1900. The force was created in the wake of the Klondike Gold Rush in response to fears that the United States might attempt to seize the region. It left Ottawa on May 6, 1898, travelling by rail and sea to the port of Glenora in British Columbia. From there, the unit made an arduous journey of 890 kilometres (550 mi) on foot and using makeshift boats to Fort Selkirk, where they established their headquarters. A detachment of 72 men was sent to the boom town of Dawson City to support the North-West Mounted Police, with duties that included guarding the gold deposits of the local banks. As the fears of an annexation reduced, pressures grew for the recall of the force. The force was halved in size in July 1898 and the remainder were finally withdrawn in June 1900.

The Royal Canadian Regiment (RCR) is an infantry regiment of the Canadian Army. The regiment consists of four battalions, three in the Regular Force and one in the primary reserve. The RCR is ranked first in the order of precedence amongst Canadian Army infantry regiments, but in a quirk of the rules of seniority, its 4th battalion is ninth.
