The Globe and Mail reports in its Monday edition that Canada attracts a wealth of internationally trained professionals as permanent residents, but too often they fail to thrive. Guest columnist Claudia Hepburn writes that many settle for low-skill work, others choose to leave. A recent Statistics Canada report found that 15 per cent of immigrants depart Canada within 20 years of their arrivals. This country must address the barriers that prevent immigrants from contributing fully to the economy. In 2019, an RBC report showed that the gap between the earnings of immigrants and their Canadian-born peers had grown by more than 250 per cent over the past 30 years. Fully 40 per cent of that gap was attributed to immigrants working in jobs below their education levels. Engineers and physicians driving for Uber show that the numbers of highly skilled immigrants in the gig economy is a national disgrace. Governments should put in place measures to enable highly educated immigrants to contribute at the tops of their skill levels. Fixing our immigrants' underemployment problem, RBC estimated, could add about $50-billion annually to Canada's gross domestic product and contribute to a regeneration of the country's productivity.
