Hiruzen is already canonically the strongest, so there is no need for feats.
Where did you get this idea? At the very most, if you are judging by the "God of Shinobi" title, then he is equal to Hashirama who held the same title. Even then, other characters like SO6P, Juubito, and Kaguya are canonically way stronger.
OT: If it is in canon episodes, then yes. If it is filler, then no. Most Hiruzen wankers will try to count them either way though.
You do know cannon is a fan made idea right?

Whats a canon?
Whats a cannon?
Wether its fillers are cannon its still accurate kishi probally has to give the ok there going off of what he has made and written already its not like a filler is in accurate so stop saying that and hiruzen was not the strongest kage the only one he can beat is the 5th hashi no one can beat tobi to fast and lord forth to fast aswell all of them have op jutsu he's strong do but no!!
They don't need an ok from Kishi for the fillers.
Being serious, no. Feats exclusively in anime are not considered canon.

why do you think that if you were writing a story would you just let people change it and alter something that could mess up your story down the line??
Prove this. Until you provide evidence, this is false.
Actually you're wrong, the anime & manga each have separate events.
Anime has directly contradicted the manga:
You must be registered for see images
You must be registered for see images
Therefore it loses all credibility & becomes non-canon.
They don't need an ok for the anime either.
