The Canadian Tamils of Sri Lankan origin is one of the fastest growing community in Canada, particularly in the city of Toronto, Ontario.  Canada is now home to more than 250, 000 Tamils, of which approximately 200, 000 live in Toronto. 
The history of Tamils in Canada goes back to the 1940s, when a few hundred Tamils migrated to Canada. Among the first Tamils to immigrate to Canada were predominantly English-educated individuals from India and Sri Lanka. Many had professional qualifications and were seeking to find better prospects for their education and talents. A substantial proportion came as graduate students and, after completing their studies, found jobs and remained in Canada.
A significant number in the 1960s and 1970s came by way of Great Britain, where they had previously settled but become disenchanted with increasing racism in that country and lured by greater economic opportunities in Canada. Since the majority of newcomers were well educated and familiar with British institutions, they had few problems adapting to Canadian life. These early Tamil immigrants were highly mobile and settled wherever they could find adequate employment. Many moved to Alberta during the boom in oil production there in the late 1970s and early 1980s.
The vast majority, however, arrived in Canada after 1983 in the aftermath of communal riots in Sri Lanka. They settled in the urban centres in Toronto (Province of Ontario), Montreal (Province of Qubec) and Vancouver (Province of British Columbia).  The Waterloo Region and Ottawa is becoming a popular immigration centre because of popular Universities and High tech. Industries.
Canada is now home to the largest Tamil population outside of Sri Lanka and South India. Within this short period of time, Tamils have established a mounting presence in multiple aspects of Canadian life: business, academic, political and social. The Tamil business community has grown in leaps and bounds, with over 2,000. in the City of Toronto.  Tamil businesses range from grocery stores and restaurants carrying South Asian foods to astrologers, marriage brokers, car dealers, computer shops, insurance brokers, and real estate and travel agents. The majority of Tamil business ventures appear to be successful, and indications are that they are growing.
