"Reducing the Length of Time a Temporary Foreign Worker can Work in Canada"
To ensure foreign workers are coming in on a truly temporary basis and that the program is used as a last and limited resort, and to encourage employers to make even greater efforts to hire and train Canadian workers before seeking temporary foreign workers, the Government will reduce how long a temporary foreign worker in the low-wage stream can work in Canada. This measure will not apply to temporary foreign workers currently in Canada on valid work permits.
