Religion in Canada encompasses a wide range of beliefs and customs that historically has been dominated by Christianity. The constitution of Canada refers to 'God'; however Canada has no official church and the government is officially committed to religious pluralism. Freedom of religion in Canada is a constitutionally protected right, allowing individuals to assemble and worship without limitation or interference. Rates of religious adherence have steadily decreased since the 1960s. After having once been central and integral to Canadian culture and daily life, Canada has become a post-Christian state. Although the majority of Canadians consider religion to be unimportant in their daily lives, they still believe in God. The practice of religion is generally considered a private matter throughout society and the state.
Before the European colonization, a wide diversity of Native religions and belief systems of the Indigenous peoples in Canada were largely animistic or shamanistic. The French colonization beginning in the 16th century established a Catholic French population in New France. During the colonial period, the French settled along the shores of the Saint Lawrence River, specifically Latin Church Catholics, including a number of Jesuits dedicated to converting indigenous peoples.These attempts reached a climax in the late 19th and early 20th centuries with forced integration through state-funded boarding schools run by both Catholics and Protestants that attempted to assimilate Indigenous children.
