Canada–India relations, or Indo-Canadian relations, are the longstanding bilateral relations between Canada and the Republic of India, which are built upon a "mutual commitment to democracy", "pluralism", and "people-to-people links", according to the government of Canada.  In 2009, bilateral trade between India and Canada was at about C$4.14 billion.  Most notably, the bombing of Air India Flight 182 by Canadian residents, killing a vast quantity of Canadian citizens, had effects on relations for about 20 years.  India's Smiling Buddha nuclear test added strains to the relationship between the two nations, with allegations that India broke the terms of the Colombo Plan.  Although Jean Chrétien and Roméo LeBlanc both visited India in the late 1990s, relations were again halted, albeit temporarily, after the Pokhran-II tests.
