The centrally located city of Moncton was selected in 1940 for the site of a logistics supply base for military facilities in the Maritimes that were undergoing unprecedented expansion as a result of World War II. Moncton Garrison was constructed in an industrial area on a railway spur line north of downtown, immediately east of the sprawling Canadian National Railways Moncton Shops facility.
The Moncton Garrison survived into the Cold War and was renamed Canadian Forces Base Moncton (CFB Moncton) in February 1968 following the unification of the Canadian Army, Royal Canadian Navy and Royal Canadian Air Force to create the Canadian Forces.
Defence budget cuts in the 1990s following the end of the Cold War saw CFB Moncton identified for closure as a formation. It stood down on April 1, 1996 and at that time was replaced by Canadian Forces Base Gagetown - Detachment Moncton, also known as Moncton Garrison, a unit of CFB Gagetown.
CFB Gagetown - Detachment Moncton supports the following units stationed at the garrison:
- 4 Air Defence Regiment
- 8th Canadian Hussars (Princess Louise's)
- 37 Canadian Brigade Group Headquarters
In April 2012, the Department of National Defence announced that Moncton Garrison would be closed in the near future. (Reference: CBC News - www.cbc.ca/news/canada/new-brunswick/story/2012/04/04/nb-defence-cuts-gagetown-moncton.html
