Experienced labour force: Persons who, during the week (Sunday to Saturday) prior to Census Day (May 15, 2001), were employed or unemployed who worked for pay or in self-employment since January 1, 2000. The experienced labour force can also be derived by excluding from the labour force those unemployed persons 15 years of age and over who have never worked or who had last worked prior to January 1, 2000 only.

Occupation (based on the 2001 National Occupational Classification for Statistics): Refers to the kind of work persons were doing during the reference week, as determined by their kind of work and the description of the main activities in their job. If the person did not have a job during the week (Sunday to Saturday) prior to enumeration (May 15, 2001), the data relate to the job of longest duration since January 1, 2000. Persons with two or more jobs were to report the information for the job at which they worked the most hours. The 2001 occupation data are classified according to the 2001 National Occupational Classification for Statistics (NOC–S 2001). This classification is composed of four levels of aggregation. There are 10 broad occupational categories containing 47 major groups that are further subdivided into 140 minor groups. At the most detailed level, there are 520 occupation unit groups. Occupation unit groups are formed on the basis of the education, training, or skill level required to enter the job, as well as the kind of work performed, as determined by the tasks, duties and responsibilities of the occupation.

Census metropolitan area: Area consisting of one or more adjacent municipalities situated around a major urban core. To form a census metropolitan area, the urban core must have a population of at least 100,000.
