Overview

Under the National Occupational Classification (NOC) 2021 system, NOC 22101 covers geological and mineral technologists and technicians. These professionals support geological, geophysical, geochemical, hydrogeological, and mining engineering fields. Common duties include conducting field surveys, running laboratory tests on mineral and rock samples, operating specialized monitoring and physical testing equipment, and preparing maps and cross-sections. They are typically employed by petroleum and mining companies, consulting geology and engineering firms, and government departments.

To qualify for this TEER Category 2 occupation, individuals usually must complete a two- to three-year college program in geological or petroleum technology, or a related discipline. Certification in geological technology or a related field is available through provincial associations and may be required by employers. Because NOC 22101 is classified as TEER 2, eligible professionals can apply for Canadian permanent residency through Express Entry programs, such as the Federal Skilled Worker Program and the Canadian Experience Class, as well as various Provincial Nominee Programs (PNPs).
