Is X Men Last Stand considers canon?

Question

X Men The Last Stand (2006)

It had no involvement of same director as X Men (2000) or X Men 2 (2004)

But is it considered canon?

What confused me is Patrick Stewart character appears to die, though Xavier is by Stewart's filmography in another 4 films at least.

Is The Last Stand canon?

Answer 1

Xavier doesn't die in The Last Stand, but it is canon.

Answer 2

Because of time travel, all X-Men films can be considered canon.

Answer 3

Considering how the movies jumped around timeline wise from Decade to Decade, I don't consider any of them Canon. I consider The Comic Books that I grew up reading to be Canon. The Movies? No, in my opinion.
