Well, looking at 3rd point, you probably should not change your position. However, I would still suggest you to contact IRCC.1. You continue to demonstrate on a reasonable basis an intention to reside in Ontario.
2. You must be employed in the approved employment position as of the date of your nomination, if you are working for the employer
3. You must continue to be employed n the approved employment position during the nomination period (until you receive PR). This means that you term if employment must remain consistent throughout the nomination period. This includes your employer, position title and duties, wage, hours of work and location.
