A new bill from the Progressive Conservatives would ban private companies from collecting Social Insurance Numbers, let victims of intimate partner violence remove abusers from a lease, along with several other changes. The changes to SIN number collection come after a major data breach at Nova Scotia Power. A government spokesperson said SIN collection will be banned for private companies unless they are authorized by the regulations. Some commercial purposes will be allowed, like landlords collecting SIN numbers. Businesses will still be able to collect SIN numbers for legitimate purposes, like reporting tax information, according to the spokesperson.
