I am flying from Toronto to Auckland with a 2 hour transfer in Vancouver. Both flights are bought on the same ticket from Air New Zealand (from 3rd party website), therefore I am not worried about getting to my final destination. The Toronto to Vancouver leg is operated by Air Canada, and the Vancouver to Auckland leg by Air New Zealand. In my experience with Air Canada, there have been many flight delays, and the Vancouver to Auckland leg flies once daily, so a missed connection would mean an overnight stay.
I know that for missed connections due to delays that were not within the control of the airline, there will be no compensation for accommodation. But what if the delay was caused by Air Canada? Their compensation page did not talk about connections, does this mean there is no protection? Also can I find anywhere a standard list of scenarios which count as delays caused by the airline?
