I found this:
Find out if you need an Electronic Travel Authorization (eTA) or a visitor visa
New entry requirement now in effect: visa-exempt foreign nationals need an Electronic Travel Authorization (eTA) to fly to or transit through Canada. Exceptions include U.S. citizens, and travellers with a valid Canadian visa. Canadian citizens, including dual citizens, and Canadian permanent residents cannot apply for an eTA.
Important: If you are stateless or if you are travelling with a travel document issued to non-citizens, such as an alien passport or a refugee travel document, you need to apply for a visa to visit or transit through Canada.
So I don't need one RIGHT?????????????????????
just my PR card
and I do have still my German Passport!
thanks!
