There is not. The example you gave is a perfect one that there is "continuity", not "canonicity". I won't bother myself to explain the difference because this should be a common knowledge by now. But I can say that things can happen in a continuity and not in another, but that doesn't make the latter "non-canon" until official confirmation/claim/statement from an official entity (Toriyama, Toei or Shueisha) not by random people (also known as "fans"). Movie characters can appear in the manga continuity if someone opens up a wormhole and bring them there. The "alternate dimension" concept exists in Dragon Ball franchise, it was established by Akira Toriyama himself in Daizenshuu 6.
Anyway, this has become off-topic. Let's drop this and return talking about
Dragon Ball Super Broly now.
Main continuity is the modern word for canon. So even if Toriyama dies, and Shueisha / TOEI continue this main story, it will still be canon.
The author however at this point is still Toriyama.
If Toriyama or Shueisha had made multiple continuities that have relevance, like you have in DC or Marvel Universe, we can have several continuities that are 'canon'.
This is NOT the case.
In Dragon Ball it's very clear what the main storyline is and what the side stories are. Toriyama has stated it clearly several times over.
What do you want? Him to make a public statement by video, declaring to the world, it's 'canon', guys?
Frankly, this "there is no canon"-statement is just made up by Youtubers that want to create the illusion everything is as important just because it fits them well, or Super-haters that want to make their claim or create an illusion GT still has the same relevance as Super. It annoys me quite frankly because it misinforms other fans.
If you believe it, it's on your account, but please don't spread misinformation.
