From our perspective, we don't see the same danger in the future. In fact, the Official Languages Act is slated for review every 10 years. So if there was a specific amendment based on a possible change in the Charter of the French Language in Quebec, adjustments could be made.
The amendments announced in Bill C‑13 even provide for a possible review of the act every five years. Therefore, if we did see a change and go back, we would also have the opportunity to amend the Official Languages Act at some point.
If I understand correctly, you are concerned that the Quebec government is being given carte blanche to amend its legislation as it sees fit and that the federal government would be required to respect it in the long run. However, that wouldn't be the case, since the review of the Official Languages Act is provided for in the bill, and that will allow us to make amendments.
