i still dont get it why he needs a transit visa if he is just changing flights at a canadian airport. I thought all you need to do is get off the plane, stay within security area and get to the next gate and board the plane again. Transit visa would be required if you were to leave the security area and perhaps the airport and then come back in time for your flight, no?
Ive never had to get a transit visa when i am just changing planes at an airport provided i have booked the entire journey as 1 booking with the same carrier.
