Iran, formerly known as Persia, is one of the oldest civilizations of the world. Iranians are a relatively new community in Canada and one that continues to grow. Their immigration to the country began in the 1980s, in the wake of the 1979 Iranian Revolution. In 2016, there were 170,755 people of Iranian origin in Canada, and another 39,650 had multiple origins, one of them being Iranian (for a total of 210,405 Canadians). From 2011 to 2016, Canada welcomed 42,070 Iranian immigrants. Iran is one of the top ten birthplaces of recent immigrants to Canada, ranked fourth after the Philippines, India and China.
