2 - Natural and applied sciences and related occupations

This broad category comprises occupations in natural sciences (including basic and applied sciences and experimental development), engineering, architecture and information technology. These occupations cover specialized middle management occupations in engineering, architecture, science and information systems; professional occupations in natural sciences (basic and applied sciences and experimental development); and technical occupations related to natural sciences (including basic and applied sciences and experimental development).

22 - Technical occupations related to natural and applied sciences

This major group comprises technical occupations related to natural sciences; technical occupations related to applied sciences and engineering. These occupations come with Training, Education, Experience and Responsibility (TEER) identified as TEER 2. Occupations classified in TEER 2, as those included in this group with a 2 as the second digit of their code, typically require completion of a post-secondary education program of two to three years at community college, institute of technology or CÉGEP; or completion of an apprenticeship training program of two to five years; or supervisory or significant safety responsibilities; or the accumulation of several years of experience in a related occupation found in TEER 3, when applicable (TEER 3 includes occupations with a 3 as a second digit in their code).

223 - Technical occupations related to engineering

This sub-major group comprises technical occupations related to engineering, including technical occupations in civil, mechanical and industrial engineering, as well as technical occupations in electronics and electrical engineering.
