Broly, The Legendary Super Saiyan is canon. The timeline of Broly's movie is not inconsistent, as it is stated to take place during the 10 day break during the Cell games. However, within that, the entire story seems to take slightly longer than is possible for them to arrive back to earth, and then go into the hyperbolic time chamber. However, we don't know exactly how long the fight (and the lead up to it) took, so it will be assumed that it took place within the time allowed, for Cell's 10 days.

Final Ruling: Canon -KidVegeta
