Thank you.
I've only examined the seasonal agricultural workers, which is a specific program. In the vast majority of cases, these workers do not want to prosecute or lay charges because their main concern is staying in the program. Most of these workers come from very impoverished situations and they know that working here is the only way to support their families. Even in the face of widespread abuses--and this is the point I make in my brief and where I outline a lot of the other studies that outline these various abuses--to workers, no matter what the conditions or what the laws, it's all irrelevant, because they're too afraid to demand their rights. For that reason there have been very few actual instances of prosecution.
However, since the health and safety act came into effect in Ontario this past year, there have been some cases brought against employers, especially in the wake of employee deaths and serious injuries. We are starting to see those come to light.
