My position name is as same as the former one and my salary is twice of my former job. So I have to send the ontarionominee@ontario.ca and inform them?Is your income same ? If yes I don’t think so you need to update them because you are not tied to any employer or job . However, if you can look closely at your nomination letter conditions and see if they said to email them if there is any change in your nomination , make sure to email them . For safer side I would recommend you to email them anyway.
