The federal government is investigating whether any of its employees were affected after the personal information of some federal, provincial and municipal government workers was leaked online.

Intelligent Transportation Systems Society of Canada was the target of an attack, and some of the information in its databases was leaked online, the company's developer Biz-Zone confirmed to CTV News.

The leaked information appeared to include the names, email addresses and phone numbers of government employees.

Biz-Zone would not specify exactly what information was leaked, but said no credit card data was exposed.

Kevin Jackson, a senior partner at Biz-Zone, told CTV's Katie Simpson that the breach occurred Tuesday morning. Within an hour of their discovering the unauthorized access that afternoon, Jackson said access to the system was shut down.

A spokesperson from the office of Treasury Board President Tony Clement said in an email that the government is looking into “any potential impacts” on its employees.

The Ontario Treasury Board Secretariat confirmed in an email that 16 Ontario Public Service employees used their government email addresses to access accounts on the ITS website.

The board said it has reset those 16 employees’ passwords as a safety precaution.

"We are not aware of any threats to the Ontario government's websites in connection with this cyberattack," the email said.
