No. The actual temporary professional work must fit the listing and the applicant must satisfy its requirements.
Compare the deliverables with the profession
Use concrete tasks rather than a matching title alone. If the contract and real job differ, identify that difference for assessment instead of hiding it in broader language.
The listed engineering credential is a baccalaureate or licenciatura degree, or a state/provincial licence; the applicant must also be a Canadian or Mexican citizen seeking qualifying temporary professional work. The principal separately needs Canadian or Mexican citizenship, prearranged work in a listed USMCA profession and the required professional qualification; permanent residence in Canada is a different fact. Resolve whether the person is a citizen of Canada or Mexico, whether the education or licence matches the specific occupation, and whether the employer controls a real temporary professional assignment. What matters is whether the duties actually performed still match a listed profession and remain professional in character, and whether the employer and the prearranged position are still as described.
