The answer is yes, but I must be careful.
In my opinion, as a lawyer, that obligation already exists in the Official Languages Act, in part VII, which could actually be improved and clarified. However, Ontario has the French Language Services Act, which, in practical terms, imposes the same obligations on the provincial government as part VII imposes on the federal government. In these circumstances, however, the provisions should be as clear as possible to avoid the possibility of challenges to those obligations.
It's important to understand why we have the French Language Services Act and why the Official Languages Act is so important. This legislation is not really necessary when a government believes in the importance of official languages. It becomes necessary when a government doesn't see official languages as all that important or as a priority, and doesn't believe they deserve to be treated differently than other languages. That is when we need these protections. Previous Ontario governments passed the French Language Services Act so that we could fall back on it today.
