You would have to ask the parliamentarians.
One of the difficulties may be technical in nature. I am not an expert in this area, but the Québec parental insurance plan applies to everyone. If members wanted to take advantage of it, they would have to give up all the other benefits that they might be able to receive. That is not necessarily to their advantage.
Do not forget the reasons I listed in my presentation. Members taking a six-month absence to take care of their babies have no replacement system to fall back on. There are no substitute members to do their jobs. So what can they do?
Suppose we had a government with a slim majority, and we have had them in some years. If several government members took parental leave, the government might well lose votes in the National Assembly. That situation has not risen yet, however. We are not at that level, but there have certainly been discussions between the members of some parties and their whips to grant shorter leave. However, we have not yet seen a member officially use parental leave in Quebec.
