I don't really understand his problem. Killing time in the MLL I read his page and it looks to me like they offered him more value than his wasted tickets.
As a one time exception, I am however able to offer you an extension on your expired credits. The breakdown will be the base fare less the $150 per ticket. Applicable taxes will be refunded to the credit card used on original purchase.
As a gesture of goodwill, we are pleased to provide each of you with an electronic travel voucher in the amount of $194.00CAD. These transferable vouchers may be used toward the base fare when you purchase Air Canada tickets for travel on Air Canada, Air Canada Express and/or Air Canada rouge, and are valid until one year from today. This means that they must be applied to new tickets purchased within that time frame, however, travel does not have to commence within the year.
The above excerpt from a post attributed to AC by the owner of the page looks like he was offered a travel credit of $88 dollars (2* 194-150) above his ticket cost with all taxes refunded. Some people just won't take yes for an answer!
