Grand Chief Greg Desjarlais of the Confederacy of Treaty Six First Nations says no referendum can overturn the treaty that encompasses most of central Alberta.

"We're tired of seeing the government pass these bills where you don't see two sentences of Indigenous inclusion, and that has to stop," Desjarlais told the media at an anti-separatist rally on the steps of the Alberta Legislature building in Edmonton, amiskwaciwaskahikan, on Thursday.

About 600 people were at the demonstration, many with flags and signs protesting Alberta's separation from Canada and the controversial Bill 54, proposed by Premier Danielle Smith's government.

"I think we're tired of being pushed around," Desjarlais said.
