Peacekeeper and Suicide Squad are Canon
While stated before the show's release, it bears repeating: The first season of Peacemaker (excluding the Zack Snyder's Justice League cameo) is canon. John Economos, Amanda Waller's sidekick, references the show's events. Peacemaker himself also makes an appearance. The Suicide Squad's canonicity is also established in the first episode.
Themyscira, Bloodhaven, Star City, Gotham, and Metropolis
The witch Cerci hails from Themyscira, Wonder Woman's home. Dr. Phosphorus was a Gotham criminal apprehended by Batman. Galaxy Broadcasting System (GBS), a Metropolis-based news company, employed Clark Kent and Lois Lane. Dr. Phosphorus's wife is from Bialia, home to Queen Bee and the Scarab that empowered Blue Beetle. 
A soldier mentions serving with Rick Flag Sr. in Jharkhanpur, home to the villain Ram Khan. Bloodhaven, Nightwing's hometown, is also mentioned, as is Star City, Green Arrow's home, where Mermaid's origins are revealed.
Sgt. Rock and Easy Company
Episode 3 reveals G.I. Robot fought alongside Sgt. Rock and Easy Company in World War II. Sgt. Rock, DC's most popular non-superhero, consistently appears in various DC multiverse iterations. Daniel Craig is rumored to portray him in a film, with Maury Sterling voicing him in this series.
Dr. Will Magnus
G.I. Robot was studied by Dr. Will Magnus, creator of the Metal Men robotics team.

The animators and co-showrunner Dean Laurie selected many of these characters.

Elizabeth Bates, Weasel's lawyer, is a reimagining of Betty Bates from the 1940s comic strip Lady-at-Law.
