Millions of credit card accounts may have been compromised after hackers stole customer information last year from computer systems of TJX Cos., the U.S. parent firm of Canadian retailers Winners and HomeSense.

TJX, which is based in Framingham, Mass., confirmed Wednesday that some customer information has been stolen from its systems, but the company said the full extent of the theft and affected customers is not yet known.

Citing unnamed sources, the Globe and Mail reported Thursday that two million Visa credit card accounts in Canada and 20 million Visa cards globally have been affected.
