This kind of show, regardless of Canadian content, comes with a built-in issue that comes to all of them if they run long enough - the little kids eventually grow up and a show based around how annoying they are as small fry stops making any sense. They have a few years left before they face this dilemma, but it's one of the reasons these kinds of programs are never on for a decade. The premise eventually runs out of time. 

Well, with one notable exception.
