An Indigenous festival taking place this week in Quebec, Canada, was condemned by the leader of a Native American group who alleged that the event was an affront. 

Dylan Whiteduck, the chief of Kitigan Zibi Anishinābeg, accused the Native Alliance of Quebec, the event's organizers, of not actually being Native Americans.

Whiteduck accused the event's organizers of distributing fake cards to people who are not Native American and argued that the group is doing more harm than good.

"This letter serves notice that what you and your organization does is fraudulent and can cause more harm to legitimate Section 35 First Nations peoples in our territory," he wrote in a letter published to Twitter last week.

"The event taking place on our unceded lands is inappropriate and unacceptable," the letter continued.

"This is cultural appropriation," Whiteduck warned.

Whiteduck was first invited to speak at the event but declined. In his tweet, he labeled the group "wannabes."

"I wouldn't be caught dead at their events or anything [that's] a part of their association or group," he told CBC Tuesday.

In his open letter, Whiteduck asked the local government to "respect and adhere to" his group's concerns and called on officials to "distance" themselves but did not elaborate on what that would constitute.
