The Canadian Conference of Catholic Bishops (CCCB) is the national assembly of the Bishops of Canada. It was founded in 1943 and officially recognized by the Holy See in 1948. After the Second Vatican Council (1962–65), the CCCB became part of a worldwide network of Episcopal Conferences, established in 1965, as an integral part of the life of the universal Church. Until 1977, it was called the Canadian Catholic Conference. The change in name reflects more clearly the fact that it is an association of Bishops.

The Canadian Conference of Catholic Bishops (CCCB) meets once a year at its Plenary Assembly.

Every two years (on odd-numbered years), the Bishops elect from among their midst the members of the Permanent Council (a minimum of 12 members) and the Executive Committee (four members: the President, Vice President and two Co-Treasurers). Every third year, the Bishops also elect the Chairmen of their six Episcopal Commissions.

A General Secretariat serves the Conference, doing the day-to-day work and ensuring the execution of the decisions taken by the members of the Conference.

To assist them in their pastoral work, the Bishops have established a permanent bilingual Secretariat in Ottawa that includes various offices and services.

It assists in coordinating activities and information.  It also maintains contacts with the Holy See and with other Episcopal Conferences, as well as with Churches, ecclesial communities, faith groups and government authorities at the national and international levels. The General Secretariat works in collaboration with the four Regional Episcopal Assemblies in Canada.

Msgr Frank Leo, Jr., C.S.S., is the General Secretary of the CCCB.
