The NOC 2021 will be published in early 2021 and will become the departmental standard for data collection and dissemination for occupations at Statistics Canada. Implementation dates for the new classification version will vary based on when programs, entities, organizations or individuals decide to use it. For example, Immigration, Refugee and Citizenship Canada (IRCC), in conjunction with ESDC, is aiming to adopt the revised NOC structure in spring 2022 for the management of temporary and permanent resident programs. These dates will be confirmed on IRCC websites closer to the date of implementation.
