MPs were open while Toronto/Peel/York were in the red zone. They will open back up as soon as that happens again. But that's not happening next week or Feb 22 or whatever. Ontario is lifting the "stay at home" order, which was actually nothing. So nothing is really changing.
Today's announcement means nothing to the GTA. It only opens up the boonies, which is great for them, because they should never have had to suffer for the natural behaviour of densely-packed cities. But nothing is changing here.
