TORONTO, Feb 27 (Reuters) - Canada's privacy watchdog

has opened an investigation into X, the social media platform

owned by billionaire tech mogul Elon Musk, on whether its use of

Canadians' personal data to train artificial intelligence (AI)

models broke privacy rules.

The Office of the Privacy Commissioner of Canada said in a

statement on Thursday it launched the probe after receiving a

complaint.

"The investigation will focus on the platform's compliance

with federal privacy law with respect to its collection, use,

and disclosure of Canadians' personal information to train

artificial intelligence models," the statement said.

The office did not provide any additional details about the

nature of the complaint.

X did not immediately respond to a Reuters request for

comment.

Musk, CEO of electric vehicles maker Tesla, is also

the founder of artificial intelligence startup xAI.

Following Musk's 2022 purchase of Twitter and its subsequent

renaming as X, the social media platform made xAI's Grok chatbot

available to its users.

Grok is an AI assistant that helps users complete tasks,

including answering questions, solving problems and

brainstorming, X says on its website.

Last week, xAI introduced Grok-3, the latest iteration of

its chatbot, which is being rolled out immediately to Premium+

subscribers on X.

Generative AI models such as Grok require lots of data to

train and develop.

Canada's privacy legislation set out rules for how

private-sector organizations can collect, use, and disclose

personal information in the course of business, the privacy

commissioner has said on its website. They include rules around

consent, disclosure, retention and safeguards.
