User blog comment:GoldMan27/The Official Detentionaire: Season 5 News Blog/@comment-207.161.124.251-20141208140016

Before every season of Detentionaire, they always televise the last one and they haven't yet aired season 4 in Canada so I'm thinking after they air season 4 from start to finish, only then a season 5 trailer come out and there will be a season 5.
