The "employee" concept used in the Canada Job Vacancy and Wage Survey is comprised of full-time employees, part-time employees, as well as permanent, casual, temporary, and seasonal employees. It also includes working owners, directors, partners, and other officers of incorporated businesses, as well as employees who work off site but report to the location, and those employees on paid leave. Industry estimates are based on the 2017 North American Industry Classification System (NAICS) Version 3.0. The following categories are excluded from the survey: "Religious organizations" (8131) within "Religious, grant-making, civic, and professional and similar organizations" (813), "Private households" (814), "Federal, government public administration" (911), "Provincial and territorial public administration" (912) and "International and other extra-territorial public administration" (919).This indicator can be used to calculate the labor demand: Labour demand is the sum of total payroll employment (met labour demand) and the number of job vacancies (unmet labour demand).
