That's a good question.
I think its enforcement can be improved by ensuring that there are more investigations. There are a number of inspections, but there are very few investigations. There are about 20 a year. I don't think that's enough.
What I see in the enforcement reports is that warnings are used a lot. It isn't necessarily the best option in the circumstances, but it's the preferred option because one of the factors considered in making the decision is the speed of the action. Of course, warnings are the quickest action, but I think it's something that should be avoided in many cases.
I believe more investigations and prosecutions should be undertaken. In cases where a prosecution isn't considered appropriate, administrative monetary penalties should be used. This is a regime that has proven its worth in Quebec. It's quick and allows for imposing a monetary penalty. Of course, the penalties aren't very big, but they can be quite significant.
If there was one change to be made, I think it would be to increase the administrative monetary penalties. Not only should they be used more, but the amount of money being imposed should be increased as well.
