I don't have an analysis I can publicly share. I have spoken with some lawyers, if I'm able to speak based on that information, sir.
My understanding covers a couple of things. First of all, given that these types of programs have already survived legal challenges--the cessation of the provision of such benefits at provincial levels, like welfare, for example, have survived legal challenges already. They've survived any challenge in that context.
I would find it actually quite surprising a) if a challenge was provided and b) if it would actually be upheld. Even if some court in its peculiar decision decided to overturn this type of legislation, I would argue that section 1 of the charter and the Oakes test would apply, and any sane-minded individual in court and judge would decide that this is an approach that ought to be taken by government, sir.
