You can begin by looking into the NOC
website and search for the NOC job code whose description would be the most comparable to your current job. You need to base your NOC code search on
job duties and not job titles.
Job duties are the most important because when submitting your proof of work experience, it has to include your job duties. IRCC will compare your job duties with those set out in the NOC job code.
You should focus on the lead statement (first paragraph) and the main duties in the NOC job code.Another option would be to use the
JobBank website. Find a job opening that matches your current job (or any previous job) and whose job duties match yours. On the job opening page, you can find the corresponding NOC code in the “Job Market Information” page.
