While the CFTA emphasizes the mutual recognition of certified workers across the provinces and territories, exceptions to Labour Mobility exist. Exceptions may be approved when there is a significant difference in occupational standards resulting in a significant scope of practice difference for an occupation. The exception must be based on a legitimate objective such as the protection of public security, health and safety.

Currently, there is a relatively small amount of exceptions considering the number of regulated occupations that exist in Canada. Jurisdictions continue to review exceptions to ensure they are current and required.
