Only if the professional agronomy work is the substance of the position and the sales element is incidental. The listed profession is Agriculturist, including Agronomist, and it requires a baccalaureate or licenciatura degree; it does not cover a seed sales representative.
The employer's description of the work decides the profession
Agriculturist, including Agronomist, sits on the Appendix 2 list with a degree as its sole credential. The question at the border is not whether the applicant is an agronomist but whether the offered job is agronomy. Crop planning, soil and tissue sampling analysis, trial design, pest and nutrient recommendations delivered to growers, and technical training of dealer staff are professional agronomic duties.
Taking orders, negotiating volume discounts and being paid principally on commission are sales duties, whatever the title says. Where a position mixes the two, the file must show that the professional work dominates, and the cleanest evidence is the employer's own written answer to a direct question about what the agronomist produces and how performance is measured. Canadian or Mexican citizenship, a temporary prearranged position and the absence of any ownership in the employer are checked alongside the profession, not instead of it.
