Replying to Canada: the worst country for domestic travel

Can someone in the know legitimately tell me why it costs me literally 10 dollars more to go from Calgary to London, than it does Calgary to Toronto?

I know we don't have much airline competition, but this is just fucking ridiculous.  There is no place in the world where domestic travel costs more.  Westjet should be ashamed of itself for even trying to call themselves a discount airline and Air Canada as a corporation would do best just to go under.
