The Diocese of Niagara is a "large" church that is composed of some 90 smaller units that we call "parishes” gathered on the traditional territory of several Indigenous peoples, including the Neutrals, the Mississauga, the Anishnaabe and the Haudenosaunee. Each parish consists of a team that includes clergy (priests and deacons) as well as lay people who exercise all kinds of different leadership. The "large" church or diocese is headed by a bishop.
