Westjet is selling tickets to Vancouver from $202 for dates departing Toronto from January 9th to early March 14. Tickets to all those cities (except Kelowna from $305) are $202-$203!
Lately, I've been finding the Matrix ITA Software search is quite inaccurate for prices, despite being powered by Google, while Google flights is more accurate.
Use Google flights to find the flight for you!
The flights seemed to be departing Mondays and returning between Monday and Wednesday.
Use this link to see not only one example but if you click on a date on the January 9th date near the top of the screen, the availability calendar with prices for all the dates will open up.
