Are you sure it was AC that cancelled the flights in question or did the Federal Gov't have a say in this as well? Some provincial airports were closed and are still closed. Also I think multiple countries around the world banned air traffic from landing in their country. Is this the fault of AC? Does the contractual obligation failure still hold true for a worldwide pandemic? Natural disaster? Who exactly would you blame for the outstanding issue with non-refundable tickets? You can't compare the kitchen renovations to airline operations during a worldwide pandemic...sorry. And my thoughts apply not just to AC but all Canadian Airlines. I choose not to pick on one over the other!
