It seems obvious to me, if one is familiar with the Supreme Court of Canada’s jurisprudence, that the asymmetrical approach is entirely acceptable and it works. Furthermore, it’s my understanding that the revised version of the Official Languages Act does integrate some of that asymmetrical approach. Indeed, it’s not the same thing for everyone: Minorities don’t experience the same situations, depending on whether they are in Quebec or elsewhere in the country. I therefore think there’s absolutely no problem with taking an asymmetrical approach.
What I do not understand about your question is the link with accountability and transparency. I admit that, for our part, we are looking at it from the outside. However, when public funds are spent, demanding accountability and transparency seems straightforward to me.
