Data and Visualizations from Pew Research and Statistics Canada:
In 2021, over 19.3 million people reported a Christian religion, representing just over half of the Canadian population (53.3%). However, this proportion is down from 67.3% in 2011 and 77.1% in 2001.
Approximately 12.6 million people, or more than one-third of Canada's population, reported having no religious affiliation. The proportion of this population has more than doubled in 20 years, going from 16.5% in 2001 to 34.6% in 2021.
In 20 years, the proportions of the population who reported being Muslim, Hindu or Sikh have doubled
Collectively, these smaller religious groups account for more than one-in-ten Canadians (11%) as of 2021, up from not quite one-in-twenty (4%) in 1971
Around a third (36%) said they never pray, and about half said they seldom (24%) or never (25%) go to church or other worship services.
Still, more than half of all Canadians (55%) in a 2018 survey said religion remains at least somewhat important in their lives
In the 1970s and 1980s, Canada’s foreign-born population was smaller, largely European and overwhelmingly Christian. In recent years, however, rising numbers of immigrants – nearly half of Canada’s immigrant population – have come from Asia, Africa and the Middle East
As the geographic origins of Canadian immigrants have shifted, so has their religious makeup.
A majority of immigrants who arrived during the 1970s were either Catholic or Protestant.
Since 2001, about four-in-ten (39%) new Canadian immigrants have belonged to religious traditions such as Eastern Orthodox Christianity, Islam, Buddhism, Sikhism, Hinduism, and Judaism.
