My answer will be virtually the same, Mr. Fortin: It will depend on the facts. I won't repeat myself, but the situation will be almost the same.
You mentioned persons who exercise parental authority. That's a term that currently isn't used in section 43. I'm a civil lawyer myself, from the Barreau du Québec, so I can tell you that it's a term specific to Quebec. There are also other descriptions. However, I understand what you're saying. You're referring to situations in which certain aspects of parental authority fall to the teacher, in monitoring and protecting children, for example. Absent the defence provided for in section 45, certain common law defences could be developed and applied in certain cases, depending on the facts.
