Without a work permit, research trainees may be refused entry to Canada by immigration authorities. Foreign research trainees need six to eight months to obtain a work permit. It is advisable to confirm that you have obtained a work permit before taking any steps to stay in Canada (buying plane tickets, renting accommodation, etc.). Mila is not authorized to provide assistance in the process of applying for an entry permit to Canada. All questions concerning immigration procedures should be addressed to Immigration and Citizenship Canada.
