A NOC, or National Occupational Classification, is Canada’s national system for categorizing and describing all jobs in the labour market. Every position is assigned a specific NOC code based on the duties and responsibilities associated with the role. While NOC codes are often discussed in the context of immigration applications, they can also be used to influence how employers support foreign national employees, how HR documentation aligns across the organization, and how positions are understood within broader workforce planning.
For foreign workers, the NOC is central because it determines eligibility for federal and provincial immigration programs. It can affect whether someone qualifies for Express Entry or whether they receive enough points under a Provincial Nominee Program. A misaligned or inaccurate NOC can be the difference between receiving an invitation to apply or not.
Beyond immigration processes, the NOC system is used to organize national employment data, including labour market outlooks, wage information, and occupational trends. Employers and HR teams may refer to this data to benchmark roles, plan recruitment, and assess labour market conditions.
The NOC also plays a central role in Labour Market Impact Assessment (LMIA) applications. Employers must correctly identify the NOC that reflects the position they are hiring for, since the classification determines prevailing wage requirements, recruitment standards, and how Service Canada evaluates the application.
When Should an Employer Confirm a NOC?
Employers are often asked to confirm a foreign national employee’s NOC, particularly when the employee is preparing an immigration application and requires confirmation of their job title and duties. In these situations, employers should proceed carefully. The NOC must reflect the actual work performed in the role, not what the employee would prefer to use for immigration purposes.
Employers must also confirm a NOC when preparing an LMIA, since Service Canada assesses the position based on the classification. Using the correct NOC ensures that the application is consistent with the role’s duties, industry norms, and labour market expectations.
Outside LMIA situations, the NOC may still influence how a position is interpreted for immigration support or internal planning in some organizations. However, in routine cases such as issuing an employment verification letter or updating job descriptions, confirming the NOC is not required. The priority is simply to ensure the job duties are accurately described and consistent across HR documentation.
Risks of Providing an Incorrect NOC
Providing an incorrect NOC can create challenges for both the employer and the employee. In the LMIA process, an incorrect NOC may lead to a refusal or difficulties during future inspections if the employee’s duties do not match the classification used.
For employees pursuing permanent residence, an incorrect NOC may result in the refusal of their application. IRCC officers compare the employer reference letter with the duties of the declared NOC, and inconsistencies can raise concerns about the accuracy of the claimed experience.
At an organizational level, an incorrect NOC can create confusion if HR records, job descriptions, and actual duties are not aligned. Ensuring accuracy supports internal consistency and clarity for everyone involved.
How to Assess a NOC
Correctly assessing a NOC begins with reviewing the actual duties performed in the role. Job title alone is not enough, since NOC classification is based on the substance of the work and not on titles or internal naming conventions.
Guidance for Foreign Workers
Foreign workers pursuing permanent residence independently are responsible for determining their own NOC in consultation with their manager or HR department.
Each NOC code falls under a specific TEER category, which outlines the associated training, education, experience, and responsibilities. Individuals can use the National Occupational Classification 2021 website to compare the lead statement and main duties of a NOC code with their own job duties. A meaningful match typically requires that approximately 70 percent of the person’s duties align with the NOC. Duties listed as “may” are optional and not required for the classification to apply.
When IRCC reviews a permanent residence application, officers will compare the employer reference letter to the declared NOC to confirm the accuracy of the work experience. Officers may also assess whether the individual’s education and background align with the employment requirements of the NOC. For example, if the NOC lists a graduate degree as a requirement and the individual does not have one, that NOC may not be appropriate for the position.
Guidance for Managers and HR Departments
For Managers, Supervisors, and HR Professionals, it is important to understand that selecting the correct NOC is typically the responsibility of the employee. This is because the NOC can determine program eligibility, and depending on the organization’s structure, HR personnel or senior managers may not be fully aware of all aspects of an employee’s daily responsibilities.
Employers are encouraged to support the employee’s review process but should not confirm a NOC on their behalf.
The employer’s role in a permanent residence application is to provide an employment reference letter that outlines job duties, dates of employment, salary, approximate hours per week, and other employment details, along with the signature and contact information of an authorized representative. If the employee has held multiple roles, each position should be listed with corresponding duties and dates so IRCC can assess the experience accurately. Employees should ensure they are confident in the NOC they are using before submission, since an incorrect NOC can have significant consequences.
Key Takeaway for Employers
If an LMIA application is not being pursued, employers should avoid confirming a NOC when the classification is unclear or not clearly established by the nature of the role. An employer’s obligation is simply to provide an accurate employment reference letter that outlines job duties and employment details. It is the employee’s responsibility to compare their duties to the NOC and determine the appropriate classification for their immigration application.
