Also, I can see from the NDP perspective, the view that the Liberals weren't holding up their part of the deal to advance NDP policy. In this circumstance, it's not like quitting a job. Trudeau wasn't Singh's boss. They had an agreement that the NDP said was mutable from the start based on their discretion. For Trudeau to bellyache about it all now is, I think, a bit silly, considering the essentially cost-free benefit his party gained from the agreement for years.
