Gaiden's, Burrito the movie, Hiniata the Movie, and all 700 chapters.
The only thing I am unsure of are the fillers. I heard he adopted stuff from them, but I don't think he ever made them canon as a whole. the first six movies I don't think are canon either.
I don't get the impulse to deny that the 693 and beyond as not being canon. Being garbage has no bearing on its canon nature. And it's not like a great series suddenly collapsed on that day. Sakura's character was finally put out of her misery in 693 when it undid all of her meaningful development, but the series was in a massive slide before that.
The war arc was awful for many reasons The Obito is cool moment came prior to that and it's probably the single most reprehensible moment of the entire series. As awful as all the pairing disasters are, Naruto's character, in particular, was being butchered to hell well before 693. I always had issues with how simplistic his ideal was handled, but Obito is cool turned it into a embarrassing joke. Him becoming a giant reactionary character happened before that Him being the descent of a one of the sage's son and, thus, the kittening all over the basic foundation of his character before that as well.
Naruto's neglect as a father and general obliviousness are bad. But the Naruto I rooted for for much of this series died long before 693.
That said, no matter how terrible, canon is canon whether we "accept it" or not.
Yes, yes, yes, to everything you said. It's perfect.
But I still had to vote 'other' in the poll at the top because I think there are really two questions here.
First, what is canon? Well, technically everything produced by the franchise, as an official Naruto product, (manga, novels, movies, anime and yes, even fillers) should be considered canon. So it's really a no-brainer. All that crap is canon, whether we like it or not.
But the second question, for me, is what is canon for NS? And though I think that Kishimoto stopped caring about his story sometime after the Pain arc, I think that NS is canon up until 699, when Naruto says "Thank you Sakura-chan," the international language of love in the manga.
(You could argue that there are som definite NS moments in the Sarada story — with Naruto acting the way a husband should with his emotional speech about not believing anything else but your feelings then saying "Let's go rescue your mom" while Sasuke said nothing — but I for me the chance for NS ended with the advent of NH and SS in 700. I feel like any NS after that is just baiting by SP or Kishimoto.)
So for me there's a canon arc for NS within the manga, but it ends with Naruto saying "I love you" in code to Sakura.
But really, the long-running, plotted and well-executed graphic novel that was Naruto stopped at the end of the Pain arc, and instead became an episodic comic that supported the anime. Aside from a few shining moments (the reunion of Kushina and Naruto being one of them) the story was traded for mini-arcs that ran like a dot-to-dot. Loosely connected moments that only added up to the barest outline of Naruto's story. Not the fully-formed, complex and multi-layered picture of Naruto's hero's journey that the manga used to be.
