The Catholic Church in Canada is part of the worldwide Catholic Church and has a decentralised structure, meaning each diocesan bishop is autonomous but under the spiritual leadership of the Pope and the Canadian Conference of Catholic Bishops. As of 2021, it has the largest number of adherents to a Christian denomination and a religion in Canada, with 29.4% of Canadians (10.8 million) being adherents according to the census in 2021. There are 73 dioceses and about 7,000 priests in Canada. On a normal Sunday, between 15 and 25 percent of Canada's Catholics attend Mass (15 per cent weekly attenders and another nine per cent monthly). Source: Wikipedia (en)
