i want to give an exaggerated example suppose ur toilet is clogged so u r looking for a plumber. u get two resumes one from an open work permit holder with just 1 year experience in canada and second from a plumber in india (i say india as I am indian) with 10 years experience, u dont get any resume from a canadian. U interview the plumber from india he is nice to talk to and u decide to hire him , u process his LMIA as u dont get any canadians to fill that position. once PR application is processed the plumber shows at ur door steps and u find out he cannot perform the work u r looking for . Now what the guy has already got PR he is happy but ur left with broken toilet. Ur only other choice will be to live in a hotel till the issue is fixed. So u see the problem. What I am trying to point out is if employers cant hire right and reliable talent they will either go under or leave canada . If they leave canada , canadians will also lose jobs example is target.
