A data breach at Tiffany & Co. is under review by the privacy commissioner. 

The Office of the Privacy Commissioner of Canada says it is aware of the issue and is ensuring the jewelry company is taking adequate steps to address the breach and protect the personal information of Canadians. 

The office says it received a breach report from the company that it is reviewing to determine next steps.

It is unclear how many Canadian accounts are affected by the breach. 

The breach also appears to have affected the United States.

A letter filed with the Maine attorney general says the breach occurred in May and was discovered in September. 

This report by The Canadian Press was first published Sept. 17, 2025.
