So it seems your were rightly refused as you don’t meet the employment requirements of the NOC. You are not a chef, you are a line cook which is a different NOC. You may be eligible under a different NOC like 63200.
You are not a chef that meets the employment requirements. If employer needs a chef then they have a LMIA and can hire someone else. Employer needs a LMIA that fits line cook, not chef if they want to hire you. So do they need a chef or cook…two different NOCs? Have you started the Red Seal exams for Chef?
Don’t know. You are not a chef, you are a cook which is a different NOC (63200). You need to see if even eligible for Red Seal based on current education and experience. This is NOC 63200 - cook/line cook
Completion of secondary school is usually required.
Completion of a three-year apprenticeship program for cooks or completion of college or other program in cooking or food safety or several years of commercial cooking experience may be required.
Trade certification is available, but voluntary, in all provinces and territories.
Red Seal endorsement is also available to qualified cooks upon successful completion of the interprovincial Red Seal examination.
Employer has LMIA for chef so they can look for chef outside Canada. Not sure who gave them advice but they should not ”waste” their LMIA. Getting another LMIA for another NOC is problematic and suspicious.
Employer can try but will need to justify why they applied for a chef in the first place, and now don’t need a chef but a line cook. Then they will need to possibly re-post the job show the hiring process. This could open up the restaurant to all sorts of questions and checks.
Apply for a new LMIA.
Even if changed, do you meet the requirements for a line cook described above?
“The first option for earning your RSE involves the following steps: Locate a culinary school that offers a professional cook apprenticeship program. Most culinary apprenticeship programs leading to Red Seal certification are three years long, and provide you with 5,000 hours of instruction and practice.”
In a nutshell
Education , apprenticeship, testing
As I mentioned before the terms chef & sous chef are too liberally used these days . As mentioned I took a three year diploma , and that was for a line cook
