Immigration Canada has a policy in place which allows certain foreign workers applying for work permits at visa offices to make the work permit application while their perspective Canadian employer applies for a Labour Market Opinion (LMO) from Service Canada. The occupation must be one listed under Canada's National Occupation Classification (NOC) at skill level O, A or B. The goal is to provide faster overall processing times since the foreign national does not have to wait for a positive LMO before applying for a work permit.
