My wife is a French citizen(France), and I am a Canadian citizen. She has a permanent resident card but it is expired. We are legally married but living apart. She has lived in Canada since 1985, but recently visited France(in December). She wants to return to Canada but is afraid they will not let her board the plane, or re-enter Canada. She has a valid passport and proof of her years in Canada. Will she be allowed to board a plane and come back to Canada with an expired pr card? If not, will she be allowed to board a plane to the US from France, where I could meet her by car in Montana or Washington State(I live in Alberta)? Would Canadian immigration let her in at the US border, if we re entered by private vehicle?
