This review is for the Maple Leaf Lounge serving the international gates here at Pearson. There's a decent food spread, featuring both hot and cold items at all times of the day - enough to make a mini-meal of things, especially if you've rushed to the airport for a late morning / midday flight without having had breakfast. There's also a decent self-serve selection of beer, wine, and other drinks, not to mention lots of room everywhere to spread out.
While this location is not quite up to the standard of overseas airline lounges such as those from Singapore, ANA, or even BA, it's still a huge step up from the mediocrity of US airline lounges, and it gets the job done fairly well.
