The big issue is safety and language. If it's a new construction site and you have all these trades at work and they don't know what each other is doing, safety is a huge issue. If they can't speak English and comprehend, it becomes a problem. Let me give you an example.
The Ministry of Labour in Ontario has a number of regulations with respect to equipment. A lot of construction trades use scissor lifts and Genie lifts. They use swing stages. In order to operate that equipment, you have to pass a written exam as well as a practical exam. If your comprehension is not there, you're not going to be able to get trained properly so that you can use that equipment. How can you be dispatched and work until your language skills are such that you can pass? You're not allowed to operate that equipment until you have that record of training, that ticket.
Health and safety are really important. If there are gaps in language and you can't get that training.... Rosemarie alluded to the underground economy. A lot of times, the underground economy is taking these people and putting them to work, and they're getting killed. I don't need to talk about some major front page accidents. A lot of times the people were not from Canada, couldn't speak English and weren't aware of their right to refuse dangerous work. They were sent to do a job that was the only work they could get and they died.
That's what happens when you send out people who are not trained properly. Never mind the skilled trades training. It's about the health and safety training. If they can't get that training and pass those tests or use that equipment, bad things happen.
