How the NOC and TEER system works
Almost every Canadian economic immigration program is built around the National Occupational Classification. When you create an Express Entry profile, apply to a Provincial Nominee Program, or request a work permit, you must state the NOC code that matches your job. That single choice determines whether you are eligible at all, which programs you can use, and how closely your reference letters need to match the official duties. Getting it right early saves you from painful refusals later, which is why a quick, accurate lookup is so valuable at the planning stage.
NOC 2021 introduced two important changes. First, codes are now five digits instead of four. Second, the old four-level skill system (0, A, B, C, D) was replaced by six TEER categories numbered 0 to 5. This finder returns both the code and the TEER for each match so you can immediately judge your options.
Reading your TEER category
TEER 0 covers management occupations. TEER 1 generally requires a university degree, TEER 2 a college diploma or apprenticeship of two or more years or supervisory roles, and TEER 3 a shorter college program or substantial on-the-job training. TEER 4 and TEER 5 cover roles needing a high-school diploma, short demonstrations or no formal education. The main Express Entry programs - Federal Skilled Worker and Canadian Experience Class - generally accept TEER 0 to 3, so seeing your TEER tells you straight away whether the flagship federal routes are open to you.
Choosing the right code
Your job title is only a starting point. Two people with the same title can fall under different NOC codes depending on what they actually do, and immigration officers assess the substance of your work, not the label on your contract. Once the finder suggests a code, open the official occupation profile and confirm that you perform a substantial number of the listed main duties and meet the employment requirements. If several codes look close, pick the one whose duties best describe your day-to-day responsibilities, because your employer reference letters must support that match.
What to do after you find your code
With a confirmed NOC and TEER you can check which programs fit. If your occupation is TEER 0 to 3, run your numbers through the CRS calculator and look at category-based Express Entry draws, which sometimes target specific NOC groups such as healthcare, trades, STEM or transport. If your occupation sits in TEER 4 or 5, focus on Provincial Nominee Program streams and pilots that accept it, since several provinces nominate occupations the federal programs exclude. Either way, gather employment reference letters that quote the official NOC duties, keep dates and hours precise, and store the occupation profile alongside your documents so you can defend your choice if asked.
Treat the result here as a fast first pass. The official NOC 2021 site is the only authoritative source for codes, TEER categories and duty statements, so confirm there before you submit anything. Combining this finder with the official profile gives you the confidence that your application is built on the correct occupation from the very start.
