"I know that if I had chosen to end it, it would have started with a call to him. I would have said, 'You know what, Jagmeet? It's not going to work.' You make those tough calls."
I honestly get why Singh chose to distance himself from Trudeau but I kind of see where Trudeau is coming from to say he should have at least talked to him first. You don't just quit your job without telling anyone and disappear. Not unless something really bad happened where you feel unsafe to do so or its just such a shitty workplace. I'm not aware of anything like that to have happened between the two. It seemed to be just a split in political priorities.
EDIT: Completely forgot about Trudeau's forced arbitration of the rail workers strike. I take back what I said above.
