A complaint that ChatGPT had collected and disclosed personal information without consent led to an investigation by Canada's privacy watchdog.

In April 2023, The Office of the Privacy Commissioner of Canada (OPC) announced it was investigating OpenAI in response to a complaint that ChatGPT had collected and disclosed personal information without consent. 

The OPC later said that several states were joining the investigation, and that it would investigate whether OpenAI obtained the necessary consent for data use, whether it was adequately transparent about that use, and whether its use of any personal data was limited to purposes that were reasonable and appropriate.
