What paperwork should a Trent Lakes surveyor carry to a port of entry?

Proof of Canadian citizenship, the credential that satisfies the profession's own rule, and a letter from the U.S. entity that names the profession in Appendix 2 wording and describes real surveying tasks. Anything not in English needs a complete certified translation, and every document should agree with every other one.

Build the file around the profession, not the person

Start with a valid Canadian passport, since citizenship rather than residence is the qualifying fact. Add the degree parchment and the transcript, and add the Ontario licence certificate showing current standing, because the Land Surveyor entry accepts either route and there is no harm in evidencing both. The support letter carries most of the weight.

It should give the U.S. entity's legal name and address, identify Priya by name and citizenship, state the profession exactly as the Appendix 2 list writes it, and then describe the work in concrete terms: retracement of disputed shoreline limits, evidence research in county records, control network design, preparation of survey plans and the person responsible for sealing them. It should set out the salary, the reporting relationship and the period requested, which may not exceed three years.

Where a state registration application is pending, say so plainly instead of leaving an adjudicator to wonder. Keep copies of anything already presented at a border, because a later inconsistency is far harder to explain than a documented change.
