EDMONTON — Elections Alberta says the separatist group at the centre of a massive voter information breach may not have shared the full list of individuals who accessed its public database.

The group, called the Centurion Project, created an app containing the private information of nearly three million Albertans, which Elections Alberta traced back to an official voter list the group shouldn’t have had.

The agency previously said it sent 566 cease-and-desist letters to those the Centurion Project identified as accessing the list while the website was active, with 21 people having full copies of the list.

Elections Alberta says it has since received information suggesting the group didn’t provide a complete list as ordered by a judge.

Two reporters with The Canadian Press accessed the public database the same day the court ordered it be taken down and elections officials and RCMP announced investigations.

One of the two reporters did not receive a cease-and-desist letter.

Elections Alberta says it has contacted the Centurion Project about whether it provided a complete list and is willing to take further legal action if necessary.

The Centurion Project did not immediately respond to a request for comment.
