recently... there are people when to different border and confessed accidentally and got deported from Canada... if you try to read some threads in this categories.... they have some examples... even changing jobs is risky... most people wait for file number before changing job... i wont recommended to change province unless that new job can support you in its pnp program or EE.... by then u will need to call to cancelled the mpnp one... Just keep in mind, misrepresentation can ban you to entered canada for 5 years. if you think you r safe and ready for this risk then go for it. no one can stop you to do what you want to.
