A retired Alberta lawyer has launched a proposed class-action lawsuit alleging one of the largest privacy breaches in the province’s history exposed the personal information of about 2.9 million voters.

The statement of claim, filed Thursday in the Court of King’s Bench in Edmonton, alleges Alberta’s list of electors was unlawfully accessed and distributed for purposes not authorized under the province’s Elections Act. 

The lawsuit names Alberta’s justice and solicitor general, chief electoral officer, Centurion Project Ltd., the Republican Party of Alberta, David Parker and unidentified defendants.
