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.

CFB Gagetown - Detachment Moncton supports the following units stationed at the garrison:
