The Boréal Convention is Quebec’s first and foremost convention on speculative fiction in literature. Publishers, readers, professional and aspiring authors alike meet up at the convention, where they can attend many activities – panels, lectures, seminars, screenings, reading sessions of all sorts and autograph sessions – in which will participate known personalities and experts in the speculative fiction and/or the literary fields. If you like to cosplay as one of your favourite characters, the Boréal Convention is also an event for you.
Starting March 15, 2016, visa-exempt foreign nationals who fly to or transit through Canada will need an Electronic Travel Authorization (eTA). Exceptions include U.S. citizens and travellers with a valid visa.
Entry requirements for other methods of travel (land, sea) have not changed.
