I'm not a huge Air Canada fan - in my experience, they aren't exactly the masters of the customer service universe - but I'll post this as a service to athletes, because Nationals is in Kelowna this year, and travel ain't cheap. Air Canada has a seat sale on until June 26th. Not to be outdone, Westjet seems to have similar pricing. Bottom Line: the cheapest flight I could get when I booked a month ago was ~$950, but you can get a ticket from Toronto to Kelowna right now for ~$700, including taxes. Hope this helps.
