Capital District Department of Public Security

The Capital District Department of Public Security (CDDPS; French: Département de la sécurité publique du district capital, DSPDC) is an executive department of the Capital District Municipal Council, the municipal government of the Canadian capital of Ottawa. It is primarily responsible for overseeing the Metropolitan Police Department, Ottawa's local civilian police, whose chief constable answers to the municipal government via the Secretary of Public Security and the Capital District Police and Crime Commissioner (PCC). The CDDPS also oversees the capital's emergency preparedness, and frequently liaises with the RCMP and Security Intelligence Service in matters of national security relevant to Ottawa as the federal capital.

The CDDPS headquarters is located at 1870 Alta Vista Dr, Alta Vista, Ottawa, near the headquarters of the Canadian government's Department of National Defence (DND).
