I don't have some "top 5" or "top 10" but i'll give it a try for my favourite cartoons.
-Johnny Test (yes, the new one. Guilty pleasure. )
-PPG Reboot (might get to watching the old one, also a guilty pleasure )
-Atomic Puppet (honestly i don't know if the internet knows about this one but it's great, but the promos on Teletoon made it look pretty bad [all promos on teletoon make some shows look bad])
