More on the *gold lounge access question ...

I know some of this is likely not clear yet, but would love any educated thoughts or input from someone like CO Insider.

Will trips from Canada to US (or Canada via US to Caribbean) be considered International?

I'm most interested in access in Canada at Maple Leaf lounge (if flying AC or if CO moves to T1 at YYZ) and then access at a PC en-route or on the return leg. That's a huge bonus for me. It drives me nuts when Canada isn't counted as international
