An employer letter that describes professional planning duties, a baccalaureate or licenciatura degree with a reliable evaluation if it was issued outside Canada, Mexico or the United States, and proof of Canadian citizenship. Any non-English record also needs a certified English translation.
Three items decide it; the rest explains them
The employer letter should state the professional title, describe the planning duties in order of importance, name the qualification being relied on, give the salary, and state the intended period of employment and where the work will be performed. A one-paragraph confirmation of employment is thin and invites questions. The credential file should hold the degree and the transcript; where either was issued outside Canada, Mexico or the United States, add a reliable credential evaluation, and where a record is not in English add a certified English translation with the translator's certification of competence and accuracy. Citizenship is shown with a Canadian passport or a citizenship certificate. Beyond those, carry the employer's corporate details and disclose any ownership interest in it. Where a professional licence exists but is not the qualification relied on, bring it anyway; explaining an omitted document afterwards is harder than presenting it.
Hypothetical example: a trail-network planner has a degree issued under a different legal name and an employer letter that uses the newer name. The first review should make a name-and-document index linking the passport, degree, marriage or name-change record, credential assessment if needed, and offer. The degree and the employer's signed description settle different issues, so neither substitutes for the other. Collect the civil link before the professional evidence is packaged, then check dates and titles together. A frequent mistake is supplying impressive academic material while leaving the name discrepancy unexplained, creating doubt that a simple record would have resolved.
