Foreign nationals wishing to work in Canada temporarily usually require a work permit.
Two of the main programs through which work permits are issued are the Temporary Foreign Worker Program (TFWP) and the International Mobility Program (IMP).
The TFWP offers work permits for candidates whose employers obtain a positive Labour Market Impact Assessment (LMIA).
A positive LMIA confirms there is a need for a foreign worker to fill the job at hand and that no Canadian worker is available to do the job.
