I've got an Aeroplan booking on a flight next March, and the schedule for the return flights seems to have changed. (No notification from Aeroplan of course...)

My flight now arrives in YYZ too late for me to make the last flight to YOW. (50 minutes on an international arrival; I could make it on my own with Nexus but I'll have my kids with me too).

Is it reasonable to expect that AC or Aeroplan will now pay for a hotel room until a connection the next day? Can that be arranged in advance?

Thanks
