The AM640 website indicates his show still airs from 7-10 PM on Corus nationwide, but he hasn't been on in two weeks, with that execrable David Cooper program taking his place instead, followed by a reroll of Ben Mulroney's morning show. 

I did hear a rerun of his stuff on the weekend, but it's odd that they would switch timeslots and not run his "Best-ofs" instead. 

Is he just on vacation or is he a victim of more Corus cuts? If so, it's a bad idea - for the price of one host and one producer, they get a show that airs on at least five radio stations. I'd call that a bargain.
