I think this is a case of false expectations,not realising the higher cost of living in Canada
the temp foreign worker program generally works best for people lookingto eventually staying in Canada. the idea of being able to send bucket loads of money is unrealistic and should be conveyed to the applicants
I could only imagine the backlash of bringing workers in and not having some sort of accommodation for them

honesty is needed on the hirers part and a little research is needed on the part of potential employees
