21.(1) The Minister may designate as an inspector or analyst for the purposes of this Act any person who, in the Minister's opinion, is qualified to be so designated.
(2) The Minister shall furnish every inspector with a certificate of designation and, on entering any place pursuant to subsection 22(1), an inspector shall, if so required, produce the certificate to the person in charge thereof.
The Minister's authority to designate inspectors and analysts has been delegated to the Department.
Section 21 authorizes the Minister to designate inspectors and analysts for the purpose of enforcing the Act. Inspectors are provided with a certificate of designation and, if asked to do so, the inspector must show this certificate when seeking entry under the authority of subsection 22(1).
Under Memoranda of Understanding between the Minister and the provincial, territorial and federal, (Labour Program at Human Resources Development Canada), Ministers administering occupational safety and health legislation, responsibility for the inspection program for the WHMIS requirements set out in Part II of the HPA has been delegated to these jurisdictions. However, Health Canada remains ultimately responsible for the administration of the HPA and regulations established under this Act.
Please refer to the discussion under section 30 which deals with the use of a certificate of an analyst in court.
