Without that knowledge, the K11 are in for a surprise. Though Naruto is strong, there's nothing preventing Orochimaru from pulling his Five Elements seal again. If Akatsuki worked together to achieve this (the Six Paths of Pain keeping the other 10 busy), including Itachi, then they can win.

So basically i think this is more like Nagato Vs Konoha 10 and the rest of Akatsuki vs Naruto.

Canon means that they possess all the information they knew at the time they encountered each other in the manga, if any. So Naruto would know about the Six Paths of Pain, but he wouldn't know who Nagato was or how he was controlling them, etc.
