As occupational standards and entry requirements for certification change over time, many provinces and territories take the approach of grandparenting workers who were certified according to a different set of occupational standards. Typically, such grand-parented workers maintain their certification and ability to practice their occupation, even though they are certified under a previous set of standards. Labour Mobility provisions under the CFTA apply to all workers who are currently certified in a province or territory.

Regulatory bodies that have concerns regarding grand-parented workers should discuss the matter with their Labour Mobility Coordinator.
