Ask for accurate dates, the role, graphic design duties and a verifiable contact or other supporting source. Include enough detail to connect the work to the profession. Do not ask a former employer to certify periods or responsibilities it cannot actually confirm.
Explain gaps and overlapping projects
Organise the chronology without hiding breaks or parallel engagements. If records are incomplete, identify the missing interval and discuss alternative evidence with counsel. A collection of undated designs should not be presented as if it independently proves three years of professional experience.
A short letter on institutional letterhead stating that the former school merged into the current one on a given date, that the program continued, and that the transcript reflects the same records does more than several pages of applicant explanation. The employer's support letter, the original credential the profession requires, proof of Canadian citizenship, and any agency or client agreement that explains where the work will physically happen. If the degree is in a related discipline such as environmental science, the file should include course descriptions showing the biological content, since the officer decides whether the degree is in the profession rather than simply whether a degree exists.
TN preparation should still explain the actual professional duties and engagement through accurate, appropriately scoped evidence, rather than use confidentiality as a substitute for a substantive job description.
