I did not exactly refer to including them in the Constitution or to amending it, but I said that we should ask ourselves whether, given its current form, access to education in the language of the minority applies to the entire education continuum.
To my knowledge, there are no briefs. The only thing I read on this is an article by Mr. Giroux from northern Ontario who spoke about the implicit guarantee of access to post-secondary training in the context of the Constitution. However, if we francophones are to benefit from section 23, they have to have French as a mother tongue.
