Education ministries are the ones giving the school boards the authority.
It's fair to say that a school board in a remote area might use an interpretation that suits its needs and change the criteria. For example, if a parent asks the school board to let their child attend the school because the parent is fluent in French and plans to raise the child in French, the board could agree to the parent's request.
The situation changes depending on the province and school board.
It would be really important for the committee's study to examine the different interpretations out there.
