Between 1991 and 2001, the number of Roman Catholics in Canada increased slightly, while the number adhering to Protestant denominations continued a long-term decline. The census enumerated just under 12.8 million Roman Catholics, up 4.8%, while the number of Protestants fell 8.2% to about 8.7 million. The largest gains in religious affiliations occurred among faiths consistent with changing immigration patterns toward more immigrants from regions outside of Europe, in particular Asia and the Middle East.
