They only rerun Steven Universe when it's airing new episodes, but those reruns don't last at all and the channel always quickly removes them from the schedule.

Maybe the reruns on Teletoon were watched by more people than the reruns on Cartoon Network. Nonetheless, Teletoon never aired reruns of the show regularly. They always removed TD from the schedule, then brought it back, then removed it again, and so on.
