Jessica Yaniv now identifies as Métis.
The serial human rights complainant and transgender activist made the announcement via Twitter.
"My Métis name is Kaskitêwâtisiwin," Yaniv, who now goes by Simpson, wrote in a post on X on Monday.
"It means "Serenity" in Cree. A word you'll choke on as you watch a Métis women — descended from buffalo hunters, la chasse-galerie, and Red River fire — dismantle the settler-colonial rot you clutch like a blood-soaked treaty."
A few minutes later, Yaniv took aim at the Catholic Church.
"Pope Francis is dead," Yaniv wrote. "But the Church's genocidal legacy lives on in every stolen Métis child, every unmarked grave, every whisper of 'residential school' ... I am a Métis women. I do not forgive. I do not forget. The Vatican falls in my memory."
A Plains Cree/Métis man later explained that far from "serenity," Yaniv's chosen name "means 'someone in the state of being blackened, by dye or stain' ... basically a reference to 'Blackface' in the Plains Cree language."
He went on to note that "Kaskitê- is the 'root stem' for black in all western cree dialects."
Later Monday night, Yaniv continued attacking the deceased pope and the institution he represented.
"You cannot exorcise the guilt; your white robes rot with shame," Yaniv wrote. "You baptized genocide and dare to speak His name. Pope Francis fell — not by hand, but by the weight of our dead."
This is not the first time Yaniv has claimed to be Métis.
According to @BarbaraDoduk, who is Métis, Yaniv first began making the claim in 2023. During one of Yaniv's many legal cases, a number of medical documents were submitted to the court, including records showing the Yaniv family ethnicity as "Ashkenazi Jewish."
Yaniv rose to fame after filing human rights complaints against five home-based beauty salons in 2018, accusing them of discrimination for not performing a Brazilian wax.
The British Columbia Human Rights Tribunal adjudicator Devyn Cousineau ordered Yaniv to pay $2,000 to the women for improper conduct and for using human rights law to attempt to extort people, arguing that Yaniv "targeted small businesses, manufactured the conditions for a human rights complaint, and then leveraged that complaint to pursue a financial settlement from parties who were unsophisticated and unlikely to mount a proper defence."
Yaniv was arrested for and found guilty of assaulting former Rebel News reporter Keean Bexte in 2020, then went on to unsuccessfully run to be the next vice-president equity and sustainability at Simon Fraser University.
