The Canadian Military Engineers (CME) (known in the Canadian Army as the Corps of Royal Canadian Engineers [RCE]) is the military engineer branch of the Canadian Forces.


The mission of the Canadian Military Engineers is to contribute to the survival, mobility, and combat effectiveness of the Canadian Forces. Their roles are to conduct combat operations, support the Canadian Forces in war and peace, support national development, provide assistance to civil authorities, and support international aid programs. Military engineers’ responsibilities encompass the use of demolitions and land mines, the design, construction and maintenance of defensive works and fortifications, urban operations (hostile room entry), breaching obstacles, establishing/maintaining lines of communication, and bridging. They also provide water, power and other utilities, provide fire, aircraft crash and rescue services, hazardous material operations, and develop maps and other engineering intelligence. In addition, military engineers are experts in deception and concealment, as well as in the design and development of equipment necessary to carry out these operations. The official role of the Combat Engineer is to allow friendly troops to live, move and fight on the battlefield and deny that to the enemy.



Following the Boer War the Canadian Government realized that the defence of Canada required more than just a single infantry battalion and a few artillery batteries as part of the permanent defence force. In 1903 The Royal Canadian Engineers were founded as the basis of the permanent military engineers, while the militia had the Royal Canadian Engineers created under the leadership of a former Royal Military College of Canada officer cadet, Lieutenant-Colonel Paul Weatherbe.[1]

World War I

One of the first tasks completed by the engineers after the declaration of war upon Germany in 1914 was for the rapid development of the Valcartier training site in Quebec. At its peak size 30,000 men were stationed here before the 1st Canadian Division was deployed to England.

When the 1st Division arrived on the front in Belgium they were accompanied by field companies of the Canadian Engineers (men recruited into the service after the start of the war were part of the Militia branch and not the regulars). These troops were responsible for construction of defences, sanitation systems, water supplies, bridging, and assisting with trench raids. Canadian Engineers also served in the Middle East fighting the Turks.

One of the most important functions of the Sappers in the war was to dig tunnels underneath enemy trenches, with which to plant explosives to destroy them. At the Battle of Vimy Ridge, several such mines were used to win the battle.

In the war the only Victoria Cross the Canadian Engineers ever received was earned by Captain C. N. Mitchell for actions on 8 October 1918 at Canal du Nord.

In total, more than 40,000 Canadians served as Engineers in the war, with 14,000 on the front on the last day of the war.

Between the wars

On demobilization, the permanent force of Engineers was changed to 38 officers and 249 other ranks. As a matter of honour, King George V, the Canadian monarch bestowed on the organization the right to use the prefix royal before its name in 1932. On 29 April 1936, the Militia and Permanent components were joined to form the Corps of Royal Canadian Engineers. On this date the Militia adopted the cap badge used by the regulars. Cipyer used from 1953 to 1967.

World War II

The formation patch worn by Royal Canadian Engineers attached to the First Canadian Army in World War II.

The Corps of Royal Canadian Engineers expanded dramatically in size to support Canada's war effort. On August 31, 1939, the Permanent Force engineers included 50 officers (with 14 seconded to other branches of the Canadian Army) and 323 other ranks; the maximum size of the Corps was reached in 1944, when it included 210 officers and 6283 other ranks.[2]

Unification and the Cold War

On 1 February 1968, the Canadian Army, Royal Canadian Navy, and Royal Canadian Air Force were officially unified as the Canadian Armed Forces. As such the Royal Canadian Engineers, Royal Canadian Navy Civil Engineers and Royal Canadian Air Force Construction Division were amalgamated. However, the new branch went under the name Royal Canadian Engineers until 1973. At that point the branch was officially named as the Canadian Military Engineers.

The present day structure of Army field units was set on 17 June 1977 with the creation of 1 Combat Engineer Regiment (1 CER), 2 CER, 4 CER and 5e Régiment du génie de combat (5 RGC).[4] The new regiments were each created from one of the squadrons of the former 1 Field Engineer Regiment.

21st century and beyond

The role of the Canadian Military Engineers has been expanding. The regular force component has been expanding the size of their units, due to the current missions of the Canadian Forces.

In April 1997, Canada's Primary Reserve reorganized into ten brigade groups and in November 1997, the first reserve Combat Engineer Regiment was created by converting an Armoured Recce regiment. A number of years later the three field engineer regiments, and seven independent field engineer squadrons were reorganized into Combat Engineer Regiments. Three Canadian brigade groups had more than one engineer unit, and one (38 Canadian Brigade Group) did not have any units at all. Now the field engineer regiments have been re-designated or amalgamated to become combat engineer regiments, and the field engineer squadrons have either been amalgamated to make new combat engineer regiments or re-rolled as generic engineer squadrons.[5]

38 CBG previously had 21st Field Engineer Squadron, based in Flin Flon, Manitoba. It was however disbanded in 1995. In 2003, the Fort Garry Horse in Winnipeg, Manitoba began hosting what will become 31 Engineer Squadron. The brigade formed 46 Engineering Squadron in Saskatoon in 2012, and is a sub-unit of The North Saskatchewan Regiment until it gains full strength.

The current deployment in Afghanistan required considerable use of Engineers for road clearance, Explosive Ordnance Disposal, Heavy Equipment, and Combat Support. To date 16 members of the RCE have been killed in Afghanistan.

In April 2013, the title Corps of Royal Canadian Engineers was brought back for the Army element of the branch.

Customs and traditions


HM Queen Elizabeth II is the Colonel-in-Chief of the Canadian Military Engineers. King George V, Edward VIII (albeit briefly), and George VI have all served as previous Colonels-in-Chief of the Royal Canadian Engineers.


King George V granted the RCE the same mottoes as the Royal Engineers.

Ubique (Latin, "Everywhere") serves as a substitution for the battle honours the Corps would have obtained if they were a line regiment.

Quo fas et gloria ducunt (Latin, "Whither right and glory lead")

Cap badge

From shortly after their creation until 1967, the Royal Canadian Engineers had a nearly identical cap badge to the Royal Engineers. This consisted of the Cipher of the Reigning monarch, surrounded by the Garter, surmounted by the crown with the words Royal Canadian Engineers on the scroll at the bottom, and surrounded by maple leaves instead of laurels.

The cap badge came to its current form after unification. Since the Royal Canadian Engineer cap badge was representative only of the army, a new one was developed. In bilingual format, the words Engineers and Genie appear on the current cap badge indicating the bilingual nature of the CME. The word Ubique also appears, confirming that the Engineers are present everywhere the Canadian Forces goes.


The CME/RCE greeting or toast is “chimo” (/ˈm/ CHEE-moh). This expression is also often used as a closing on correspondence between engineers. The word chimo is derived from the Inuktitut greeting: “saimo” (saimu) that means “hello,” “goodbye,” “peace be with you,” and similar sentiments. This salutation was used in the Ungava region of northern Quebec and shares the same derivation as Fort Chimo (today Kuujjuaq) on Ungava Bay in northern Quebec. The current spelling and pronunciation is based on a Caucasian adaptation of the native language. On April 1, 1946, the Canadian Army assumed responsibility for the portions of the Alaska Highway that lay with Canadian boundaries. This section of the Highway was renamed the “Northwest Highway System” and the responsibility for maintenance was given to the Royal Canadian Engineers for the next twenty years. The soldiers of the CME/RCE adopted the greeting of "Chimo" and in 1973 it became the cheer of the CME.[6]

Engineer Prayer

The Engineer Prayer was created for 2 Field Engineer Regiment by Major Hugh Macdonald, the unit's padre. It goes as follows:

Almighty God, we pray thee to bless the Canadian Military Engineers. May our bridges always stand, and our charges never fail, our members be ever loyal, and our officers worthy of their loyalty. May we work diligently in all our purposes and be skilled in our trades; steadfast for Queen and Country everywhere. Amen. [6]

Patron saint

The Canadian Military Engineers have no patron saint but Engineers often take part in artillery celebrations honouring St. Barbara, the patron saint of the artillery. Engineers, along with the artillery and miners, celebrate her feast day on December 4.St. Barbara is the patroness of artillerymen, fireworks manufacturers, firemen, stonemasons, against sudden death, against fires, and against storms (especially lightning storms).

Canadian Military Engineers Association

The CMEA <> is the non-profit group of serving and retired military and civilian members of the Engineer Branch. Membership is $2 per month payable, by pay allotment Y012 for military members or by cheque, to the Branch CWO. The address is shown on the membership application <>. Branches are distributed across Canada, or wherever like-minded members gather to promote military engineers and engineering.


The CME/RCE has a number of equipment for use in supporting the Canadian Forces at home and on deployment overseas.

Canadian Forces School of Military Engineering

The Canadian Forces School of Military Engineering (CFSME) at CFB Gagetown in Oromocto, New Brunswick is responsible for the conduct of 85 different courses that span all ranks and occupations within the Field, Construction and Airfield Engineer organizations. CFSME is the Canadian Forces Centre of Excellence in Engineer Training and home of the Engineers. [7]
