The Ontario Workplace Safety and Insurance Board is taking another look at 50 claims filed by temporary foreign workers employed on farms.
President Jeff Lang also announced changes will be made for injured workers who are unable to return to their jobs.
The WSIB pays workers 85 per cent of their salary if they are hurt on the job and unable to return to that role, but claws back money that is earned from other work.
Lang says that is not fair because migrant workers who return home after injury usually earn far less in their countries than if they worked the same job in Ontario full time.
Lang says he is sorry for what he called the province's unfair treatment of injured migrant workers.
"These are some of the most vulnerable people, they came to work in Ontario, they got hurt, they got sent back to their home countries, and they got dinged for not being from Ontario," Lang told The Canadian Press.
"And quite frankly, that's just wrong, so we're going to make it right."
The announcement follows an appeal tribunal ruling that the board mistreated four claimants.
