No. The listing accepts a baccalaureate degree or a state or provincial licence, so a Canadian engineering degree alone satisfies the qualification. A state licence governs what he may sign once working, which is the employer's practice question rather than the officer's classification question.
The degree qualifies him; the licence governs practice
The USMCA Appendix 2 entry for Engineer lists alternatives: a baccalaureate or Licenciatura degree, or a state, provincial or federal licence. An engineer holding a Canadian bachelor's degree in civil engineering meets the qualification without any licence, provided the position itself is engineering work. Officers look for a match between the degree field and the duties; a civil engineering degree paired with structural inspection or highway design is a clean match, whereas the same degree paired with contract administration duties invites questions about whether the job is professional engineering at all.
State law separately determines which engineering activities require licensure. The applicant and employer should check the responsible state board's requirements for sealing drawings or taking responsible charge of designs, including any examination, experience or comity rules. The employer should say in the letter whether he will work under a licensed engineer initially, because that clarifies the proposed duties without treating TN classification as a state licence.
