Quebec's medical schools must take steps to counter a bias against foreign-trained doctors, Quebec's human rights commission said Tuesday.

Results of a three-year investigation show that the selection process for residency positions discriminates against international medical graduates.

In 2007, every doctor who graduated from a Quebec university was offered a residency position in this province, while two thirds of foreign applicants were rejected.

As many as 85 residency positions were left unfilled in Quebec, important to aspiring doctors because it is the last step in getting a licence to practice medicine in the province.
