On September 21st, 2021, Employment and Social Development Canada (ESDC) and Statistics Canada released the new National Occupational Classification (NOC) 2021 for data collection purposes. ESDC’s programs are expected to start the implementation process of the NOC 2021 in late 2022 as survey and census data based on the new classification becomes available.
The NOC 2021 Version 1.0 overhauls the “Skill Level” structure by introducing a new categorization representing the degree of Training, Education, Experience and Responsibilities (TEER) required for an occupation. The NOC 2021 Version 1.0 also introduces a new 5-digit hierarchical structure, compared to a 4-digit hierarchical structure in the previous versions of the classification. The NOC has been developed and maintained as part of a collaborative partnership between Employment and Social Development Canada and Statistics Canada. This revision is extensive; the last structural revision was NOC 2011.
