Regarding that figure you said for the injured workers, there are actually more unreported cases of injured workers who are being sent back home. Those were the reported cases of injured workers.
I would like to mention this. Women migrant workers who get pregnant while working here in Canada get fired, so they don't have access to health care. One worker who I talked to last month lost her baby. She had to hide her tummy and put on a girdle so the employer would not see that she was pregnant, because she was afraid of being fired, and what happened is that she lost her baby.
