If I am going to apply PR via Express Entry outside Canada, and able to find an employer to give me an employment offer with LMIA. I just wonder if I must report duty to that employer once I arrive in Canada? What if I have some last minute change which makes me can’t go to work or if I find another employer, is it legal to do so? Or will CIC revoke my PR if they find out I didn’t report duty to the original employer?
