Canadian Hindus generally come from one of three groups. The first group is primarily made up of Indian immigrants who began arriving in British Columbia about 110 years ago. Hindus from all over India continue to immigrate today, with the largest Indian ethnic subgroups being Gujaratis and Punjabis. This first wave of immigrants also includes Hindu immigrants who were of Indian descent from nations that were historically under European colonial rule, such as Fiji, Mauritius, South Africa, Guyana, Trinidad and Tobago, Suriname, and parts of coastal Eastern Africa. The second major group of Hindus immigrated from Bangladesh, Nepal, Bhutan, and Sri Lanka. In the case of Sri Lankan Hindus, their history in Canada goes back to the 1940s, when a few hundred Sri Lankan Tamils migrated to Canada. The 1983 communal riots in Sri Lanka precipitated the mass exodus of Tamils with over 500,000 finding refuge in countries such as Canada, the UK, Australia, Germany, France and Switzerland. From then on, Sri Lankan Tamils have been immigrating to Canada in particular around Toronto and Greater Toronto Area. A third group is made up of Canadian converts to the various sects of Hinduism through the efforts of the Hare Krishna movement and their Gurus during the last 50 years.
