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 1992 updates

The National Occupational Classification (NOC) classifies more than 25,000 occupations by skill type and skill level to provide an accurate picture of the constantly changing Canadian labour market. Among its many applications, the NOC is a vital work tool for census surveys and labour market research and analysis, such as the Canadian Occupational Projection System.

Many programs and systems rely on the NOC for labour statistics including immigration, unemployment insurance, employment equity, and training. Counsellors in career planning and vocational rehabilitation will appreciate the easily updatable loose-leaf binder format and poster-size graph matrix that clearly illustrates the classification system.

The NOC replaces the Canadian Classification and Dictionary of Occupations.
