Yes. If you are a lawful permanent resident of the U.S. (Green Card holder) and cannot get a passport from your home country because it does not issue passports to permanent residents of other countries, you can apply with:
- your U.S. Refugee Travel Document (I-571), or
- your Permit to Re-enter the United States (I-327).
Enter the document number in the passport number field on the eTA application form. Your eTA will be electronically linked to your travel document.
Note: Whenever you travel to Canada, regardless of the method of travel, carry your valid Green Card to show your status as a lawful U.S. permanent resident.
