The Toronto Transit Commission has confirmed that the personal information of tens of thousands of employees may have been compromised as a result of a ransomware attack on its systems last month. 

The TTC, which operates Toronto’s bus, subway, streetcar and paratransit systems, said in a statement that the compromised data includes the names, addresses and Social Insurance Numbers of 25,000 past and present employees. The agency said it’s continuing to investigate whether a “small number” of customers and vendors have also been affected.
