Bring the employer's letter describing the position, duties, and duration, proof of Canadian citizenship, and evidence of the applicant's professional qualifications matching the role. Additional supporting documentation depends on the specific profession.
Prepare the packet as if presenting it in person
Because the admission request happens at the point of entry rather than through an advance visa application, the documentation needs to be complete and organized for direct presentation. Confirm the employer's letter covers duration, duties, and the employer's identity clearly. Keep copies of professional qualifications on hand rather than assuming they will not be requested.
Assemble the packet as though it will be handed across a counter and read immediately, because it will be. Proof of Canadian citizenship, the employer letter describing the position, duties, arrangement for payment and period, and evidence that the applicant holds the qualification the profession requires form the core, with additional material depending on the specific profession. Organise it in that order and keep it in one folder rather than spread across a phone and a suitcase.
Bring copies of professional qualifications rather than assuming they will not be requested, and where a credential was issued abroad bring the evaluation too. Anything not in English needs a certified translation. Keep a duplicate set at home.
