No. The actual duties and the specific credential entry need assessment. Canadian or Mexican citizenship and qualifying temporary professional work remain necessary. A laboratory’s hiring criteria may overlap with immigration requirements, but they are not a substitute for reading the applicable entry.
Keep occupation and workplace distinct
A hospital, research institution and commercial laboratory may assign different activities to similar titles. Ask the manager to describe the testing and judgment involved. The employer’s setting does not independently prove that the work falls within a particular listed profession.
A degree from an institution outside Canada, Mexico and the United States requires a reliable foreign-credential evaluation; do not treat a résumé abbreviation as that evaluation. Begin with a position-specific duty table: mark which tasks the person will perform, their approximate importance, and the deliverables the employer expects. Start by comparing the ordinary weekly duties with the exact profession selected, then ask which record proves the worker’s qualification. The treaty list sets a separate minimum under each profession, and the horticulturist line is satisfied by the degree it names rather than by a professional licence. An officer who sees a letter promising floor duties, with no state licence and no certification, has reason to question whether the professional arrangement is genuine.
