I have no idea what anything referring to “canon” means.

Canon is the official storyline. The way the characters fit in, the vehicles and equipment used.
Star Wars for example. Its canon that Lule was Vader’s son. It’s canon that Yoda was a badass.
Original Lucas Canon was that after the Return of the Jedi, the Jedi Academy was reestaished, Chewbacca’s kid and Han andeia’s kid were training there together. Disney bought he franchise and threw everything put and retconned…. a retroactive change… eveverything after Return of the Jedo and so are new canon, a new official storyline
In Marvel it’s canon true admantium was made by accident and nobody knows how.
Head canon is just WHT someone ages up in their head for themselves when setting isn’t examined official, when it’s not in the story.
