The
National Occupational Classification, or NOC, is a systematic
taxonomy in English of all occupations in the
Canadian labour market. As a Canadian government publication it is concurrently published in French as
Classification nationale des professions. Organized into two volumes, it describes 923 distinct occupations in terms of aptitudes, interests, education, physical activities, and other qualifiers. A separate index further classifies over 25,000 job titles from the listed occupations.
