Interestingly, in the Battle of Gods guide that goes over "all the information you need to understand the movie," which has a Toriyama's direct involvement, quote...
Original work/story/character design Akira Toriyama dragon ball legend
The first new movie in about 17 years, “Dragon Ball Z: God and God”! Introducing the story. You can enjoy the movie even more by reading this book, which includes a variety of content such as Toriyama's rough illustrations and explanations of the "Dragon Ball" world!!
...has filler events from the Z-Anime, notably mostly Toriyama sourced content like the Kai Hierarchy, Pikkon, and most
notably, the Bardock considered Goku's father. Toei's.
This is interesting, because Dragon Ball Minus and it's retcon happened in April 2014, whereas this Guide was released in conjunction with the Battle of Gods film in March 2013.

This implies Toei Bardock was considered canon in relevance to the manga (as Toriyama went on record to say he made the film with the manga in mind) until he literally changed his mind within that year whilst coming up with Jaco the Patrolman. So it wasn't even something Toriyama had in mind when he worked on Battle of Gods, which is interesting to me. Also it implies that some of the filler events are in fact manga canon events, which we already kind of know, but it's interesting to see in "real time" how Toriyama considered how much of the Anime's content was in the Manga.
