A wrong NOC entered by an employer on an OINP employer form is a common clerical error, and group members suggested a two-track fix depending on your application stage:
- If you haven't submitted yet: contact OINP and have the employer send the corrected form right away, before the file goes in.
- If you've already submitted: since the correct NOC is consistent everywhere else (experience letter, job offer letter), you can submit a Letter of Explanation (LOE) clarifying that the employer form contains a typo and pointing OINP to the correct NOC used throughout the rest of the file.
Members who'd been through similar situations described OINP as generally cooperative with this kind of clarification, since it's a documented clerical mismatch rather than a substantive discrepancy in your actual work history.
