An employee at Coast Capital Savings inadvertently emailed a list of the insurance claims of 464 clients to about 75 Metro Vancouver media outlets.

The email attachment included names, postal codes and the amounts of property insurance claims, but no social insurance numbers, addresses or account numbers.

A letter would be sent out to all the affected clients, said Philippe Sarfati, Coast Capital's chief risk officer.

"I can assure them that the content of that attachment in no way contained any information that may be used for identity theft," he said Tuesday.

Sarfati said Coast Capital, based in Surrey, B.C., is doing a comprehensive security review to make sure such a thing cannot happen again.

One of the affected policyholders, consultant Judy Lightwater of Victoria, B.C., is not particularly worried about her name being on the list.

"I don't even pretend to try and think that I have any privacy left," said Lightwater, who had filed a claim for water damage to her Nanaimo office. "I think that's just the state of the world at the moment."

The B.C. Office of the Information and Privacy Commissioner said it would look into the breach to see whether it warrants a full investigation.

Coast Capital Savings has about 120,000 active policyholders, according to Sarfati.
