Do we have an actual list of the champs that have been confirmed as canon in the current state of leauge? Cause it's annoying to start talking to people about the lore and pointing out a champ then people say their lore is outdated and not canon anymore.
Pretty much all the bios that were updated in an event(starting with burning tides) are canon(at least for now,they said that if one of these champs gets a VGU,they might change the bio again,even if they'd try to avoid this) and the same goes for all champs that were released/got a VGU with a bio+color story(which is standard for every champ starting with Kindred),as well as Varus and Annie.
So all in all these champs have "canon"-bios at the moment(sorted by faction)
Bilgewater
and soon 
(and maybe Fizz)
Demacia 
Freljord
Ionia
(though Karma will receive an updated version of her lore soon)
Noxus 
Piltover
Runeterra
Shadow Isles
Shurima
Targon
Void
Zaun
& 
also have color stories that were released after the retcon,so they are most likely canon as well.
The way I see it, until it is contradicted, whatever has been written is canon. No matter how old.
I mean on the Universe part of the website all lore is updated.
