The fact that applications were actually cancelled is shocking... bruh!!It'll take some time to introduce reform. Quebec's immigration reform bill was proposed in Feb 2019 and was passed in June 2019. Some of the language being used here is similar to what is being said about EE now:
That being said, Canadian immigration in general has shown itself to be a lot more considerate than Quebec's system, so maybe we can expect a 4-5 month delay once a new bill is proposed. At the end of the day, all the hypothesizing in the world isn't going to make any difference. Just sit tight and wait till ~September. Keep documents ready. Start preparing for GRE/GMAT if you want to go the 'buy-your-PR' route. Focus on what you can do to maximize your chances instead of incessantly dwelling on what you can't have any control on.
