I am a Lao citizen. I am planning to buy a one way flight ticket from Vientiane to St. John’s NL (Canada) and I will passed in Seoul incheon (Icn) airport.
Do I need a visa? Thanks, Siri
Lao citizens need a temporary resident visa (this is the official name Canada gives to visitor visas) to visit Canada. You need to obtain the visa before you depart.
You do not need a visa to transit through Seoul and remain in the airport transit area. You are allowed to leave the airport on Korea's transit tourist program for a brief tour of the city, if you have sufficient time between your flights.
You will likely be denied boarding, or denied entry to Canada, if you have a one way ticket.
Timatic, the database which airlines use to verify passenger travel documents, states in part:
Korea (Rep.) (KR)
TWOV (Transit Without Visa):

(For Canada, visa exemptions exist but none apply to you, so they are not shown here.)
- Visitors not holding return/onward tickets could be refused entry.
