A PRTD is required for permanent residents of Canada who are outside the country and do not have a valid PR card to return. When applying, timing is critical, as the document must be obtained before boarding a flight to Canada. Applicants should ensure they meet the residency obligation of 730 days in the past five years, as this will be closely reviewed. Supporting documents, such as proof of residence, tax records, employment history, or family ties in Canada, strengthen the application. It is also important to provide accurate details and explain clearly why a PR card is not available, whether due to loss, expiry, or first-time issuance.
