NOC 22101: Geological and mineral technologists and technicians

Geological and mineral technologists and technicians provide technical support and services or may work independently in the fields of oil and gas exploration and production, geophysics, petroleum engineering, geology, mining and mining engineering, mineralogy, extractive and physical metallurgy, metallurgical engineering and environmental protection. They are employed by petroleum and mining companies, consulting geology and engineering firms, and by governments and educational institutions as well as by a variety of manufacturing, construction and utilities companies.

Express Entry eligibility

• Skilled work (TEER 0 to 3): yes, TEER 2.
• Canadian Experience Class: counts as skilled Canadian work (1 year in the last 3 years).
• Federal Skilled Worker Program: counts as skilled work (1 year of continuous work in the last 10 years).
• Federal Skilled Trades Program: not one of the eligible trades.
• High-wage occupation (from November 3, 2026): no. No high-wage add-on, and a job offer in it earns no CRS points.

TEER 2: Occupations that usually need a college diploma, an apprenticeship of 2 or more years, or supervisory duties. Every program has other requirements too, such as language test results and, for FSW, a points test.
