These are qualified workers, who have a job offer from a Canadian employer, are admitted into Canada to work in a specific position and location for limited period. The job offer has to be confirmed by the Human Resources and Social Development Canada (HRSDC), which determines that there is a shortage of Canadians to fulfill the position.
A person can start working in Canada within a few months of receiving the job offer. The best advantage is that Canadian work experience and presence in Canada on a valid Work permit help the candidate score additional points under the Federal Skilled worker point system. Thus, it is easier to convert temporary status into a permanent one, once you are in Canada on a Work permit.
Live-in caregivers can stay in Canada permanently if they meet certain requirements.
