My point being, you won't be able to access the "AC lounge" using *G credentials as you would going to MLL in LAX, SFO, LGA. And as I said earlier, the only exception is access for Aeroplan credit card holders which would not be accepted at any other UC.
You couldn't access it as a UA*G when it had AC branding and an AC desk either ... and the OP is flying business class so no *G needed for access.
