Yes, of course.
WestJet did announce that it would voluntarily refund the airline tickets, but within six to nine months. That's a very long time. So the refunds haven't started yet.
On the Air Canada side, to my knowledge, the tickets that are refunded include those for European flights. That said, the refund policy that has been applied is not necessarily the one prescribed by law. Air Canada will reimburse European passengers who have purchased a ticket for one of its flights, not Canadian passengers. However, under European law and regulations, it is the destination and origin of the flight that matters, not the place where the ticket was purchased.
