I envy your travels! My cousin and I used this airport last year, too, and we checked out the facilities. Everything there is great. There are chapels and interfaith prayer rooms in both terminals. They’re completely isolated from the hustle and bustle, and there’s absolute silence inside. I don’t recall any separate rooms with video game consoles for teenagers, but the free high-speed Wi-Fi works perfectly throughout the entire complex. They’ll be able to surf the web without any problems. I also recommend checking out the Toronto Pearson Airport (YYZ) information portal in advance because it lists all the available information. We read through it all back then, and it really helped us find our way around. Like, we found the right terminal five minutes after getting off the plane. Have you decided how you’ll get into the city? And did you book a taxi, or are you thinking of taking the train?
