No. The actual work must fit a listed profession and the Canadian or Mexican principal must meet its prescribed qualifications. A commercial description does not choose the immigration category.
Read the tasks beneath the label
Separate the professional analysis from administrative, sales or delivery responsibilities in the real scope. Do not rewrite those duties merely to resemble a listed profession. A client’s preference for one category cannot replace the factual assessment.
The listed alternatives are a baccalaureate or licenciatura degree, or equivalent professional experience supported by a statement or professional credential attesting to five years in management consulting or five years in a specialty related to the consulting agreement. For TN purposes the question is whether the whole of the work is professional geological practice, described clearly enough that an officer reading the letter sees one qualifying assignment rather than a mix of professional and technician tasks. The Scientific Technician/Technologist entry does not require a baccalaureate; it requires theoretical knowledge of a listed discipline, the ability to apply it to practical problems and a role in direct support of a professional in that discipline.
