Changes to the National Occupational Classification

Employment and Social Development Canada (ESDC) and Statistics Canada work collaboratively to complete National Occupational Classification (NOC) updates and revisions. Historically, the departments undertook content updates every five years and structural revisions every ten years.

To establish the frequency of updates and revisions, the departments strive to reconcile the need to keep the classification up-to-date with the ability to reflect occupational changes over time, while minimizing disruption to statistical coding and time series analysis. As part of continuous improvement, ESDC and Statistics Canada agreed to update the NOC on a more frequent basis following the publication of the 2016 version of the NOC.

You can find a summary of all the changes that took place since 2001 below:

NOC 2016 updates

NOC 2016 version 1.3 – December 2019

Summary of changes

The National Occupational Classification (NOC) has been developed and maintained as part of a collaborative partnership between Employment and Social Development Canada and Statistics Canada.

This update, released on December 16, 2019, mainly focuses on the standardization of the lead statement and of the main duties sections across the classification. Therefore, these sections were modified for most unit groups (sometimes going through only small alterations) in order to improve consistency and ease of reading.

Some specific changes were made to the lead statement, main duties, and employment requirements sections of NOC 3222 – Dental hygienists and dental therapist.

The main duties of NOC 7201 – Contractors and supervisors, machining, metal forming, shaping and erecting trades and related occupations, NOC 7202 – Contractors and supervisors, electrical trades and telecommunications occupations, NOC 7203 – Contractors and supervisors, pipefitting trades, NOC 7204 – Contractors and supervisors, carpentry trades, NOC 7205 – Contractors and supervisors, other construction trades, installers, repairers and servicers, NOC 7301 – Contractors and supervisors, mechanic trades, and NOC 7302 – Contractors and supervisors, heavy equipment operator crews were also modified to add one generic change.

Finally, job titles were added to or deleted from some unit groups across the classification.

NOC 2016 version 1.2 – December 2018

Summary of changes

This update to the classification was completed in response to the legalization of cannabis for non-medical use. This has resulted in twenty-five new job titles being created in NOC 2016 to reflect new occupations in the cannabis industry.

NOC 2016 – October 2016

The purpose of the 2016 revision of the National Occupational Classification (NOC) has been to: update the classification to incorporate emerging occupations and new job titles while maintaining historical comparability; remove redundant or obsolete job titles to optimize readability and navigation of the NOC; incorporate editorial changes; integrate the concept of inclusions at the unit group level; and add NOC major and minor groups definitions.

The structure of NOC 2016 remains unchanged from that of NOC 2011. No major groups, minor groups, or unit groups have been added, deleted, or combined, though some groups have modified labels or updated content.

Job title changes at the unit group and minor group levels and updates to the definitions of some unit groups reflect added information, correction of terminology to correspond with current usage, and the evolution of some occupations and where they are classified.

Many new job titles have been added to NOC 2016, which arise as the division of labour in Canadian society evolves, creating new jobs and new specializations, and as technological change brings with it new terminology. Some of the titles added to reflect such changes are: geodesist, medical archivist, crime scene examiner, corrosion technologist, video game tester, and biomass plant technicians. Other added titles are modified versions, or alternatives, that appeared in previous versions of the NOC and have been added to help users find particular occupations. For example, power plant stationary engineer appeared in earlier versions of the NOC; operating engineer - power plant has been added.

To clarify the boundaries between occupations, a few titles have been re-assigned to a different unit group in NOC 2016. The impact of this on the comparability of data between 2011 and 2016 is negligible. For example, Admission director – health care has been moved from Managers in health care (0311) to Other administrative services managers (0114). This change will have a minimal impact on the unit groups affected, and provides a more appropriate placement. In all other cases where titles have been moved, this was done to clarify the boundaries and improve content description of these unit groups. For example, the titles ‘tax collector’ and ‘collector of taxes’ were being coded in Collectors (1435) rather than in Employment insurance, immigration, border services and revenue officers (1228).

With the transition to a paperless environment and content digitalization, significant format changes were made to the list of job titles contained in the NOC. To optimize the use of the NOC, redundant or obsolete job titles were removed. In the past, titles appeared in both in natural order (e.g., travel agent) and in inverted order (e.g., agent, travel). Inverted titles used a comma as a separator in the title string making it easier to find titles in a paper publication. As this concept became outdated and redundant in web publications and data files, more than 10 000 duplicates entries were removed for the NOC 2016.

The NOC is structured in accordance with the Generic Statistical Information Model (GSIM): Statistical Classifications Model. In order to comply with the demands of GSIM, the NOC was revised with the addition of inclusions to supplement the existing illustrative examples and exclusions. Inclusions are borderline cases for the unit group. They are presented separately in order to clarify the contents of the class. Note that creation of Inclusions does not change the boundaries of any NOC unit group.
