AM uses T2 @ LAX and the current lounge is Air Canada Maple Leaf Lounge (which is quite nice). There is self-serve alcohol, food buffet, showers, business facilities, and phone charging machines. The lounge decor is in good condition and has great views of the runway.

I checked in online, but if you stop by the check-in desks, they'll give you a pass to take to AC. There are a few Qatar Airways passengers currently in the lounge, too.
