I've seen a lot of conflicting information out there, so hopefully someone here can help clarify

Flying YYZ-JFK-MIA
Tickets for both legs are coded Business (I) and I have no oneworld status

Can anyone confirm, will I be granted access to AC in YYZ? And during my connection in JFK? Or will neither lounge grant access?

As previously discussed, the language on the AA AC Access webpage is a bit confusing...
