I am not a lawyer either, so at one point I will ask Madame Tremblay to comment on the role that preambles play. But I am a former journalist, and when I was a journalist I found it very useful to have a preamble for a piece of legislation to explain in simple, direct sentences what the purpose of the legislation was.
Often you would have a piece of legislation.... In this case the clauses are fairly simple, but if there are amendments, there can be a whole list in the piece of legislation saying that section 41 of this legislation is amended in the following way, and section 68 of another piece of legislation is amended in the following way. In simply reading the legislation, it is very difficult to understand sometimes what the purpose is. This is not the case in this piece of legislation.
