To add, i bet AC/AC Rouge has upped their 767 part prices significantly when WJ needs a part from stores. I guess WJ should've done more research regarding upcoming unexpected maintenance even if a part is changed once every 20 years. AC will always have an upper hand in the international market, new 787's and 777 incoming regularly, old 767's going to Rouge. WJ should consider the 787, might have to wait a bit due to backlog now.
Kinda unfair AC can go to Bombardier, get CSeries at a peanut price, and here Wesjet's gotta save up for decades to expand their fleet because their a private firm. The government should be ashamed, the logistics of Canadian travel both domestic and international is very poor, and expensive, even if you're flying YYZ-YOW!
Hopefully WJ can look long term.
