If anyone listened to CBC's West of Centre podcast, they had Nenshi on the other day and he said that not only is the Trudeau - Notley - Singh alliance fictional (which is kind of obvious) but that in meetings, each would spend the first 20 minutes bashing their counterpart haha.
He also said that Singh and Notley had a falling out over Trans Mountain and don't really see eye to eye these days (which again, is pretty plain to see).
