The employer letter with a duty breakdown, evidence of the designation or degree, and proof of Canadian citizenship. Add evaluations and certified translations wherever a credential was issued abroad.
The letter carries most of the weight
The employer letter should name the position, describe the professional accounting duties in order of importance, name the qualification relied on, state the salary, and give the intended period and the location of the work. Ask for a proportion-of-time breakdown as an attachment; it is unusual, and it answers the question an officer is going to ask anyway. Evidence of a professional designation should come from the issuing body and confirm current standing. Where a degree is relied on, bring the parchment and the transcript, with an evaluation and a certified English translation if either was issued outside Canada or the United States, since a translator's certification of competence and accuracy is expected. Add the employer's corporate particulars and a written note of any ownership interests held.
Hypothetical example: a nutritionist is recruited by a U.S. food manufacturer to review ingredient labels and formulate menus for an employee wellness programme. The first review produces a checklist matching each claimed fact to a record: passport for citizenship, degree and transcript for the qualification, and an employer letter for duties, pay, location, and duration. Have the company sign the letter through a person who can explain the role if contacted. A résumé helps give context but does not settle the occupation. Sequence the work by obtaining the credential records before asking for the final letter, so its wording can identify the exact qualification relied on. Files commonly falter when the letter gives only a title or repeats the résumé without explaining the proposed professional work.
