Algonquin College is investigating a cyber attack that breached one of the school's servers.
It's unknown at this time how many current and former staff and students may be affected, but the college says it could be thousands.
It's also unclear which data was specifically accessed.
Algonquin discovered the hack several weeks ago and say they acted immediately to secure the server.
An investigation into the scope of the breach and how it took place is underway.
