I hadn't heard that this was likely to happen. Any Canadians here able to weigh on whether this was expected or is a normal procedure for your elected officials?
I suppose standard procedure in a Westminster parliament is to have a non confidence vote and an election - which is what the opposition parties said would happen when Parliament sits again. Poroguing parliament and having a leadership race is probably a way to try and avoid that or at least go into the election with a less unpopular leader.
Proguing parliament is probably the best thing for the liberal party to avoid an election with an unpopular leader. But I don't think it's good for Canada as it states down Trump's tariffs
