South Asian Canadian community was done between 2005 and 2007 by Statistics Canada, with results derived from the 2001 Canadian census and a following survey which found that Canadians of South Asian ancestry were 28% Sikh, 28% Hindu, 22% Muslim and 16% Christian, and 4% irreligious. Other religious such as Jainism, Buddhism, and Zoroastrianism practiced by Canadians of South Asian heritage formed the remaining 2%. The irreligious proportion of 4% among South Asian Canadians is statistically significant, as this figure climbs to approximately 17% when surveying all Canadians. The 2011 Canadian census found that the religious breakdown of Canadians with South Asian ancestry was 29.1% Hinduism, 28.5% Sikhism, 24.5% Islam, 11.8% Christianity, 4.3% Irreligion, 1.1% Buddhism, 0.1% Judaism, and 0.6% other. This marked the first time in census records where Sikhs did not form the largest religious group amongst Canadians with South Asian ancestry. Religious affiliation in the South Asian Canadian community varies greatly based on national background. Based on the Statistics Canada report done between 2005 and 2007 with results derived from the 2001 Canadian census, Indo-Canadians are split between Sikhs (34%) and Hindus (27%), Muslims (17%), Christians (16%), Irreligious (4%), with Jains, Buddhists, and Zoroastrians forming the remaining 2%. The majority of Pakistani Canadians (90%) and Bangladeshi Canadians (87%) profess to follow Islam, while the majority of Sri Lankan Canadians are Hindu (64%) with a significant minority following Christianity. Nepalese Canadians tend to mostly follow Hinduism with few of them following Buddhism. Additionally, religious distributions among certain South Asian Canadian ethnic groups also vary; 80% of Tamil Canadians are adherents of Hinduism, a large majority of Punjabi Canadians (86%) are Sikh, while most Bengali Canadians (74%) are Muslim. Religion is found to play an important part in the lives of many Canadians from South Asia and serves as defining point in their identity, as with many people. Religious institutions such as gurdwaras, mosques, mandirs, koils and churches have often serve as points for the community. Religion can also play an important role in the marriage of some young Canadians from South Asia (who were born in Canada or in a country from South Asia). Some families believe that the couple must share the same religious heritage, which may also include caste, although this is becoming outdated. In recent years, Canadians from South Asia have opened private schools in order to preserve their religious heritage (as with Catholic schools),
