The Plenary Assembly is a meeting of the members of the Canadian Conference of Catholic Bishops (CCCB), being approximately 90 Bishops from across Canada; each gathering of the  Bishops in plenary thus represents a solemn and momentous event in the life of the Church in Canada. The Plenary Assembly takes place once per annum (customarily in September) and lasts one week. The meeting involves discussion on a broad range of topics affecting the Catholic faithful in Canada. It includes reports from the CCCB’s various commissions and committees as well as the President’s annual report and an address by the Apostolic Nuncio. Decisions taken by the plenary assembly represent the highest instance of authority within the CCCB.  Between plenary assemblies, the deliberations and decisions of the Conference are undertaken by its Permanent Council and the Executive Committee, both of which are mandated by and respond to the Plenary Assembly.
