31 Combat Engineer Regiment (31 CER or "The Elgin's"),[1][2] is currently a combat engineer regiment of the Canadian Armed Forces, supporting 31 Canadian Brigade Group of the 4th Canadian Division (formerly Land Force Central Area). It consists of two squadrons: 48 Engineer Squadron in Waterloo, Ontario, and 7 Engineer Squadron in St. Thomas, Ontario. The Elgin's existed before the Confederation of Canada, tracing their origin to 1866 when the Militia Act officially created the 25th, Elgin, Battalion of Infantry from five local militia companies.
