The TDSB data impacted by the data breach dates back as far as 1985.

Information such as health card numbers, home addresses and phone numbers for students who attended a TDSB school anytime between 1985 and 2017 may have been impacted, while medical information, principal notes and dates of birth for students attending between 2017 and December 2024 may also be among the information compromised in the breach.

The school board told Global News that while it did not have total numbers for staff impacted, it said first, middle and last names, employee numbers and TDSB email addresses of some staff were impacted.

It also said those whose data may have been accessed or acquired include teachers, principals, office staff, superintendents, guidance counsellors and classroom support staff like educational assistants.

The U.S.-based provider of cloud software said on its website that some “personally identifiable information,” such as social security numbers and medical information “was involved” in the breach and was working with “urgency” to identify those impacted.

Canada’s privacy commissioner, Philippe Dufresne, announced last week he was communicating with the company in response to the data breach, adding this past Monday he was “concerned” about the potential impact that the incident could have on personal information of students across the country.

He said his office is working to obtain more information  about the breach and also provide PowerSchool information about its breach response and reporting requirements under Canada’s privacy regulations.

In a statement to Global News, PowerSchool said it recognized the “significance of this incident and are sincerely regretful that it occurred,” and has worked to prioritize transparency and direct communication with its customers.

Asked to confirm if the numbers reported in the BleepingComputer post were accurate, the company said it did not “intend to downplay the numbers reported in this article,” but it stressed it expects the majority of customers impacted, “in fact, more than three quarters,” did not have social security numbers exfiltrated.

The company added it would be offering two years of complimentary identity protection services and two years of complimentary credit monitoring services for all applicable students whose information was involved.
