We don't. Our firm doesn't. We are an Alberta-based company.
As I say, we've heard of these companies, and they are sneaking into the construction industry. Typically they've been known in the unskilled sector. Meat packing is probably one area, and it's been in the news--workers were brought over from other countries and paid very large sums of money to work--but in the construction sector there isn't a lot of opportunity for a company to skew outside of those wages.
Although I'm saying that, some companies we call ask if they can't just pay this worker the minimum wage. It's up to us if we want to work with a company like that, and our response is no. But they are out there.
We, as a company--and we're just one company--can keep our eyes on that and make the government aware, but I don't know the answer. That's a good question--how to eliminate companies from paying below the wage that they should be.
