This is a busy station. You can connect to GO transit from here and being the end point for the subway you have to get off whether you like it or not. There's your usual news stand on site, but this station lacks any other options for food. Maybe with the new expansion they're currently building something will be added.
Look carefully for your bus stop. With the current construction at the station they have been moving some of the stops around and doubling up some routes into the same stop.
