Ottawa: India’s envoy to Ottawa says Canadians need to rebuild the country’s brand as a destination for bright minds, lamenting that a number of international students have died after being exploited. High Commissioner Sanjay Kumar Verma told the Montreal Council on Foreign Relations that exploitation is undermining the role Indian students in Canada play in helping both countries advance their technological knowledge. Canada’s international student program has come under intense scrutiny after a sharp rise in study permits in recent years, leading the federal government to implement a two-year cap on foreign student admissions. Last year, there were more than one million international students in Canada.
