刚刚前两周收到的邮件： All modes of travel (air, land, rail, marine) You must be prepared to provide your valid passport or other travel documents and proof of your valid status as a lawful permanent resident of the U.S. to airline staff at check in and to a Canada Border Services Agency border services officer when you arrive at a Canadian port of entry. These documents will be used to determine admissibility to Canada as you no longer require an eTA. For documentation considered acceptable as proof of your valid status as a lawful permanent resident of the U.S., please consult the section Required documents for lawful permanent residents of the U.S. to travel to or through Canada on page 2.
