Tiresome Wendy Mesley missed the cut. Yay. 
This would have been a perfect opportunity for CBC to shock & awe us by giving Ghomeshi a surprise come back on CBC (CBC must miss the ratings he brought to CBC's "Q", ratings they've never come close to again by using new hosts). Heh heh - Or at least Evan Solmon (who didn't deserve to be fired in the first place, unlike Ghomeshi, imo). 
However, the four chosen make for a very "2017 values" roster with gender parity and 50% visiible minorites represented. A transsexual added to the mix would have made the choice PERFECTLY p.c. for 2017 (although some skeptical viewers would have viewed such a move as "gender parody"). Close, but no cigar!
