How to get Air Canada to pay for overnight stay
 

Air Canada have moved a connecting flight forward by 28hrs meaning I have to pay for 6 people to stay overnight and taxis or car hire.
They have offered a double connecting flight but as there reputation is poor for connecting flights I am forced to take the overnight stay.
How can i get them to pay for it...they moved the flight not me!

Thanks
