Whether you are an economist analyzing labour market data for a specific occupation or an employment counsellor helping someone determine what type of training to take, occupational descriptions help us understand an occupation using a standardized language.

Lead statement

This section provides a general description of the content and boundaries of a unit group and indicates the main activities of occupations within the unit group. It also indicates the kinds of industries or establishments in which the occupations are found. The list of places of employment is not always exhaustive, but can assist in clarifying the occupations described and in differentiating them from occupations found in other groups.

Example titles

Example titles are the job titles commonly found within a group. The titles are intended to illustrate the contents and range of the occupational group. This list is an extraction of a more expansive listing of alphabetical job titles found in the NOC index of titles.

The most reliable information on regulatory requirements for occupations is found on provincial regulatory organizations and licensing authorities’ websites.

Additional information

Some descriptions include additional information to give details on:


The exclusions section helps to clarify the boundaries of a unit group by identifying similar groups or related occupations, such as supervisory groups, that are separately classified.
