Why are you not able to check the websites of each province, and check their policies/rules regarding sponsorship under provincial nomination ?
All have websites. You can easily find out what's false and true. Do it yourself. Only you can decide what's best for you in your situation so why are you asking others (specially without checking the official websites which are on internet).
Are you going to just take other's words rather than checking yourself ?
Moving without checking and researching each provinces' immigration policies is simply very foolish decision.
Sorry to say this, but an educated person should be able to research and find out on their own BEFORE asking EXPERTS (such as immigration law firms).
