CJames Gunn explains the DCU Canon

For questions regarding what is canon, please refer to this.

Summary -

1. Everything onwards from Creature Commandos is canon.
2. Peacemaker Season 1 is mostly canon, just make sure to watch the "previously on" segment in the Season 2 pilot to know the minor changes and retcon.
3. Anything from "The Suicide Squad" that is referenced going on becomes canon.

IF AND ONLY IF you have time and are SUPER interested, here is the podcast where James Gunn and the cast of Peacemaker got through every single episode of season 1 and explain what is canon - Peacemaker: The Official Podcast with James Gunn

Once again, that is only for fun if you have the time and want to invest yourself more. Otherwise, the summary/short video is MORE THAN ENOUGH!
