Mary Hill Police Storage Facility

The Mary Hill Police Storage Facility, colloquially known as the Mary Hill Depot, is a large, secure evidence storage facility in Port Coquitlam, the second-most populous city of Coquitlam County, itself one of seven counties in the Lower Mainland region of the Canadian province of British Columbia (BC).

The depot is owned, operated and guarded by the Lower Mainland Constabulary (LMC), although two other law enforcement agencies (namely, the British Columbia Provincial Police and the Royal Canadian Mounted Police) contract with the LMC to use the facility. The facility is used by the three forces for securely storing contraband and other criminal assets seized during operations in and around the Lower Mainland region of BC.

The Lower Mainland Constabulary owns and operates two other secure evidence storage depots, both located in Delta, South Fraser County (namely the Annacis Island Depot and Burns Bog Depot). They both serve the same purpose as the Mary Hill Depot; however, the Mary Hill Depot is by far the largest and most important of the three: the combined total available space for evidence storage in the Annacis Island and Burns Bog Depots is barely half that of the Mary Hill Depot alone. Nevertheless, all three evidence storage depots are subject to equally strict security protocol.
