Ministry or department (also less commonly used secretariat, office, or directorate) are designations used by first-level executive bodies in the machinery of governments that manage a specific sector of public administration. These types of organizations are usually led by a politician who is a member of a cabinet—a body of high-ranking government officials—who may use a title such as minister, secretary, or commissioner, and are typically staffed with members of a non-political civil service, who manage its operations; they may also oversee other government agencies and organizations as part of a political portfolio. Governments may have differing numbers and types of ministries and departments. In some countries, these terms may be used with specific meanings: for example, an office may be a subdivision of a department or ministry. The federal Government of Canada uses the term department to refer to its first-level executive bodies. In Canada, first-level subdivisions are known as provinces and territories. Five of the ten provincial governments use the term ministry to describe their departments (Ontario, Quebec, Saskatchewan, British Columbia, and Alberta) but the other five, as well as the three territorial governments, use the term department. Despite the difference in nomenclature, both the provincial and federal governments use the term "minister" to describe the head of a ministry or department. The specific task assigned to a minister is referred to as his or her "portfolio". British government departments In the United Kingdom, all government organisations that consist of civil servants, and which may or may not be headed by a government minister or secretary of state, are considered to be departments. Until 2018, the term "ministry" had been retained only for the Ministry of Defence and the Ministry of Justice. On 8 January 2018, Prime Minister Theresa May announced that the Department of Communities and Local Government would be renamed at the Ministry of Housing, Communities and Local Government to emphasise her government's prioritising of housing policy.
