Well, while it isn't canon, some things from the Z movie is canon.

1. The new warlord chopped off Z's arm, even if Z isn't real.

2. Sakazuki, Borsalino, and Kizaru joining when they did.

Oda even said, that the Z movie is only non canon because it might confuse manga fans. I swear, Z should at least have been like Shiki, canon, appearing in an non canon movie.
