Canada ETA For Bulgaria, Mexico, South Korea, Israel Citizens CANADA ETA FOR BULGARIAN CITIZENS Bulgarian citizens who want to visit Canada for a short time must obtain a Canadian eTA visa. In 2015, the Canadian government launched an online visa waiver service for qualifying countries. Any other mode of transportation, it should be noted, will necessitate a separate travel authorization. Bulgarian citizens, on the other hand, do not need a visa for tourism, business, or transit.
