Yep, as BS65 said you can move to any province. The Canadian Charter gives you this right.
However, up until the point you land you must have an intention to stay in your sponsoring province. Intent can of course change.
There have been serious issue with PnP runnerups in Canada - almst everyone do the same unless they realize that they are traceable and can be found guilty of cheating. You have to show intent ..otherwise, you may be having trouble when dealing with your province for immigration card and citizenship issues. This is what I have done and I can assure you that PnP can be handled easily, this way.
1. Convince PnP officers at time of dealing with express entry that you are very much interested in settling down there - they need tax payers over there and are not concerned what in fact you do.
2. Do register yourself when you land with SERVICE CANADA, open a bank account and get a phone.
3. Send time in finding job, use portals and their services and keep record that you tried to get a job. You can easily arrange a interview - keep record of that interview, this will be your alibi for not having job there, in future.
4. Your apartment can not be booked over phone, so you will be staying in guest houses / hotels / AirBnB but keep record , receipts etc.
5. You are buying groceries now, paying cash - keep all receipts.
6. Move slowly to your province in second month , one month is enough for this drama. But keep paying your bills. Hydro and Rent.
Arrage your stay in province you want to move in - after two months, pack up and shift permanantly.
No lawyer can challenege this in case you are taken up by PnP
