I don't think this fight is over. Toya is resistant to cold and we still haven't seen him use prominence burn, a move we know he has from the war arc.
My guess is next chapter, Toya uses prominence burn and Shoto has to protect endeavor's sidekicks from it. He takes massive damage but survives while Toya is pushed to near death by the attack. He probably burns off his arms and legs, but I think Horikoshi will keep him alive longer so that Endeavor can apologize to him.
