Which non canon characters were made canon in Dragon Ball recently?
It's debatable whether the end of DBZ can be considered canon. Hence, the character of Uub wouldn’t technically have been canon until the Tournament of Power arc.Bardock has always been canon. If it weren’t for him, Goku and Raditz wouldn’t have existed. Super Saiyan Bardock is the one who isn’t canon.Broly like you said, will be made canon based on the trailer for the new Dragon Ball Super movie.
