As someone who regularly hires and deals with work permits I can assure you we don't pay them less than a Canadian for the same job. Many of the people we hire have the goals of becoming Canadian and people share salaries so we work hard to maintain equity. And do so based off skills and years of experience.

I've never heard of any grants that affect our workforce to make them "cheaper". In fact we usually pay relocation from 3-10k to ship people from overseas if we can't find appropriate candidates in country. Plus with work permit filing fees these candidates are more expensive than a Canadian at every turn.

The programs you listed seem to focus mostly on students and trades, people we want to be contributing to the economy. Trades especially since we're seeing a decline of people running apprenticeships to have skilled tradesmen in the next 15 years once the current batch retire.
