Canada has introduced NOC 2021.

New TEER system replaces NOC skill levels
Rather than the current approach of categorizing jobs based on skill type, the Canadian government will now categorize jobs based on a new Training, Education, Experience and Responsibilities (TEER) system.
Currently, NOC skill levels fall under four categories: A, B, C, and D.
NOC 2021 moves away from this approach and introduces the TEER system which has six categories: TEER category 0, 1, 2, 3, 4, and 5.
TEER 0
Management occupations.
TEER 1
Completion of a university degree (bachelor’s, master’s or doctorate); or
Several years of experience in a specific occupation from TEER category 2 (when applicable).
TEER 2
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
Occupations with supervisory or significant safety (police officers and firefighters) responsibilities; or
Several years of experience in a specific occupation from TEER category 3 (when applicable).
TEER 3
Completion of a post-secondary education program of less than two years at community college, institute of technology or CÉGEP; or
Apprenticeship training of less than 2 years; or
More than six months of on-the-job training, training courses or specific work experience with some secondary school education; or
Several years of experience in a specific occupation from TEER category 4 (when applicable).
TEER 4
Completion of secondary school; or
Several weeks of on-the-job training with some secondary school education; or
