Until He Goes to Rehab

Breaking News

A radio station in Canada is trying to do what Scooter Braun can't ... get Justin Bieber into rehab ... but the station has a secret weapon.

Hot 89.9 in Ottawa just radioed out to its listeners -- Justin is persona non grata on its airwaves UNTIL he checks himself into a facility to get badly needed help for drug abuse.

So far Justin has laughed off all attempts to get him into treatment.
