Appendix 2 lists Forester and Sylviculturist, each requiring a baccalaureate or Licenciatura degree, but it does not list crew leaders, equipment operators or planting supervisors. The listing decides who qualifies; the company's org chart does not.
Match each person to a listed entry before anyone books travel
Hypothetical example: a Stoneham-et-Tewkesbury forestry-services contractor wins a stand-tending contract with a Maine landowner and wants to send its sylviculturist, who holds a forestry baccalaureate, plus two experienced crew leaders. The sylviculturist fits the Sylviculturist entry, and her degree meets its rule. The crew leaders, however skilled, hold no listed profession: their experience does not attach to any Appendix 2 category, and there is no general skilled-worker entry to borrow from.
The company can send one person under TN and must find another arrangement, or none, for the others. The second requirement is that the sylviculturist's work in Maine be professional work in that field rather than crew supervision relabelled. Ask the Maine landowner for a letter describing silvicultural prescriptions, monitoring and reporting, and keep the contract terms consistent with that description.
Canadian citizenship is required for each applicant; a permanent resident on the crew is not eligible regardless of role.
