The Assembly of Manitoba Chiefs says a non-confidence vote on whether to remove suspended Grand Chief Arlen Dumas will proceed today as planned.

That’s despite an announcement by Dumas on Wednesday that he will seek trauma-based treatment.

Sandra DeLaronde, an advocate for missing and murdered Indigenous women and girls in Manitoba, said that quote “"If he was sincere about addressing the trauma … he wouldn't have waited until the 11th hour."

In June, DeLaronde was the driving force behind a letter signed by 200 people.

It included lawyers, doctors, sitting federal and provincial politicians, which voiced support for Dumas's accuser and called on the AMC to launch an independent inquiry and trauma-informed process that focuses on victims.
