TRP is a short-term permit which is issued to foreign nationals who demonstrate the compelling need to enter Canada for a short period of time. The time duration for which temporary visa is issued can range from weeks or months as decided by the issuing officer.
Those foreign nationals who are rendered inadmissible might be issued TRP if they or their health is not a threat to Canadian public. They must have valid reason to travel to Canada.
The temporary resident permit can be applied at a Canadian Visa office outside Canada, at a port of entry in an airport or land border crossing between the US and Canada.
