Canadian permanent residents are able to use their permanent resident card (PR card) in order to enter the country. However, if a permanent resident does not have a valid PR card and needs to enter Canada, they may be eligible to apply for a permanent resident travel document (PRTD).
A travel document lets the U.S. government know about your travel plans. This is for anyone who is not a U.S. citizen but is living in the USA. You can use a travel document instead of a visa as proof of travel authorization. You must get your travel document before you leave the country.
