Last week, he took off Thursday and Friday, leaving Alex Pierson in his place and her producer Mike Drolet taking over her show. Will it happen again? Mulroney announced on Wednesday that he will be flying to Vancouver (pointedly noting it was on WestJet and not Air Canada!) with his mother for a charity event. 

Mulroney is, so far, the only local Corus host that has a YouTube channel for his show, where you can watch the various segments and interviews with video. Not sure why, but it does not appear to be available live, which would make more sense. The produced pieces are chopped up segments from his show, and feature him and his guests chatting about issues. 

Would Alex Pierson get the same treatment if she sits in on his show? I don't see any evidence of it, but it's something to check after this Friday's program is over.
