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 2006 updates

NOC 2006 – 2006

This volume represents the updated version of the National Occupational Classification (NOC 2001 edition), first published in 1992. The NOC 2006 is considered a minor update with no revisions to the classification structure. The changes include the addition of new titles and the modification of descriptive content for certain NOC groups. Some changes were also made to reflect consistency between the English and French versions and to correct errors. The update affected approximately 200 of the 520 NOC unit groups.

The original introduction to the NOC 2001 is included with this edition, as the structural changes made for the 2001 revision are still in effect. Since then new titles have gained prominence and much of the 2006 update focused on integrating them in the classification. Certain titles that may be classified in many different groups remain problematic. However, with access to increasingly sophisticated search mechanisms, it is expected that some of these titles will be added to the classification in the next revision projected for Census 2011.

The summary below does not identify specific content changes but provides an indication of the magnitude and types of changes that were made.
