It beats landing in LAX at the same time as a three jumbos from the far East and having to line up with all those non-English speaking people as they try to gain admittance to the US.

I agree, it is a pain to have to come early, especially in YOW where this no lounge (and practically nothing else) once you've cleared US immigration. But I'd prefer to be waiting, sitting down, confident that I'm on my way, than to wait standing in a long, slow-moving line-up at the other end.
