"Very recent immigrants who have been in Canada five years or less, that is, who landed between 2001 and 2006, had the most difficulty integrating into the labour market, even though they were more likely than the Canadian-born population to have a university education. In 2006, the national unemployment rate for these immigrants was 11.5%, more than double the rate of 4.9% for the Canadian-born population."
