Iin my interpreation, IF and when Wynne resigns, the train has left the station, the party with the largest number of seats, Hudaks Pcs in this scenario, form governement and continue as government until losing a confidence vote. If they lose a confidenve vote there is an election. Or Premier Hudak, doing as Premier Wynne did, could ask the L-G for an election, before facing defeat on a confidence motion.
That's why Wynne's resignation as premier would be dangerous.
To quote the House of Commons website again:
if an election gave no party a clear majority and the prime minister asked for a fresh election without even allowing the new Parliament to meet, the Governor General would have to say no. This is because, if “parliamentary government” is to mean anything, a newly elected House of Commons must at least be allowed to meet and see whether it can transact public business.
But that is if the incumbent premier asked for a fresh election. If she resigns, and a NEW premier asked for a snap election without ever meeting the House, would the Lieutenant-Governor grant the request? He shouldn't, in my view, but can we be sure?
