Here´s the drill (you can always double check with them by email:
ontarionominee@ontario.ca):
10.MAKING CHANGES AFTER APPLICATION SUBMISSION
You must notify the OINP of any changes to information provided in your application,
including (but not limited to):
o Change in contact information
o Change in immigration status (expiration or change in temporary work permit)
o Change in family composition due to:
Marriage or common-law relationship
Birth of a child
Change of custody of a child
Divorce/separation
Death
After you submit your application, you will only be able to make changes to your telephone
number, email address and country of residence online. You can do so by logging into the
OINP e-Filing Portal and clicking on “My Profile” on your main page. After the change has
been made, click “Save”.
For all other changes, you must complete the Change of Personal Information form. Once
completed, you must send the form by email as an attachment to
ontarionominee@ontario.ca indicating in the subject line “Application Change Notice – [File
number]”.
You must not send in additional documents and/or information to the OINP unless you
need to notify the program of a change, or unless you have received a request for additional
information. In both cases, you must contact the OINP via email. Paper documents will no
longer be accepted by mail, fax or in person.
