Herbert Grubel, an immigrant to Canada and professor of economics at Simon Fraser University, argues that Canadians increasingly worry about the current immigration levels. According to Grubel, almost half of the population believes that 500,000 immigrants per year are too much for Canada, and 75% of people are worried about potential housing shortages and the extra demand for social services due to this new plan. In addition, despite many Canadians welcoming immigrants and appreciating their benefit to the economy, they believe the housing market in Canada can only absorb much higher prices.
