Doesn't Transport Canada or the Canadian Transportation Agency (CTA) require that airlines must give a reason for a delay? It's somewhat hard to believe that no reason was given nor were the employees aware of the reason for the delay. If it's true that weren't told the reason then a complaint to the CTA is in order.

As for your request for compensation I doubt that is going to be granted. You said you had transportation arranged for your original arrival time. Of course it is inconvenient for someone to drive to the airport at a late hour to pick you up but the choice to take a taxi home was yours. As for the missed day of work because you arrived home so late...I'm not even going to comment on that. You might get a travel voucher to use on a future flight but that's all you should expect.
