The situation was such that the 2nd Canadian Division made its brigades responsible for the provision of "Trench Police" to perform traffic control duties.
On September 13, 1939, the Royal Canadian Mounted Police (RCMP) requested and received permission to form a Provost Company using volunteers from its ranks.
For most of 1940, 1 Provost Company was stationed in England, but was involved in the battles during the fall of France (Brest, Laval, Sable and Chateaubriant).
During 1943, 1 Provost Company became involved in operations in Sicily (Pachino, Valguarnera, Assoro, Agira, Adrano and Regalbuto) and after the crossing into Italy on 3 September 1943, the company continued its support of the I Canadian Corps as part of the Eighth Army as Allied forces crept northwards from the toe of Italy.
In the Cassino area of Italy, the Canadian Provost assisted the British CMP on "Highway 6", where 11,000 vehicles were handled every day.
The Canadians were part of twenty-four provost and traffic control companies and two Special Investigation Branch sections that were attached to the Eighth Army.
Shortly after the Normandy landings in June 1944, the 2nd Canadian Line of Communications (LoC) Provost HQ and six sections were deployed in Northern France on traffic control duties.
