The Canadian General Standards Board (CGSB) develops standards for NDT personnel certification in Canada.

It covers various NDT methods and levels of proficiency, and professionals need to pass examinations to be certified under the CGSB standard. Standards such as the ASNT are American, while ASME is an engineering standard not related to NDT personnel. The DNR Standard does not apply to NDT personnel certification.
