It's a question worth asking, after two major Toronto radio talk shows remain without permanent hosts, in one case more than half a year after the last moderator left. 

Bell Media's "News Talk Today," the recent replacement for the Evan Solomon Show, has seen an endless parade of hosts since Solomon left for a job in the U.S. Some days it's Deb Hutton. Other afternoons, Graham Richardson from Ottawa is in the chair. And occasionally, even Mark Twohey returns to sit in. You'd think by now they'd be able to find a permanent host. (Hey, Jamil Jivani is available...naw, it would probably never work out!)

Far less explicable is "On Point," the show that airs on AM 640 from 7 PM -10 PM. It was started with Alex Pierson behind the mic several years ago. Then she took a leave of absence after suffering exhaustion, starting April 1st. November will mark 8 months since she left, and returned in the 9 AM slot. But On Point still doesn't have a permanent voice.

Many nights. it's veteran Arlene Bynon hosting. Sometimes Rubina Ahmed-Haq gets the time. And then there's Rob Fai, who turns up occasionally, when David Peck isn't on the air. 

Bynon is a veteran news person, but the others have a specific area of expertise - Haq specializes in finance, Fai has a sports background and Peck is a magician. 

It's weird that in more than half a year, Corus still hasn't found someone to take over the show permanently and continue to have a seemingly never-ending round of musical chair hosts. Can't they just find someone and give the show a proper focus? What's taking so long?
