I was just going to say that $1,000, depending upon the size of the firm, I suspect would be an issue. Canadian employers, by and large, do not like to break the law, so most firms, I'm sure, would not put themselves in the position of being fined $1,000 a day, regardless of what the cost would be.
I think that in fact the issue at hand is more whether or not replacement workers should be banned. That would have a fundamental impact on every firm in the federal sector, and through that, most employers and most citizens of Canada.
