Mailing error in Newfoundland and Labrador reported to privacy commissioner

ST. JOHN'S, N.L. - Six beneficiaries in Newfoundland and Labrador's prescription drug program have received letters from the Department of Health and Community Services that were intended for someone else.

The government says it has contacted the six people affected by telephone.

The six letters are from 21,000 mailings sent on June 29 extending beneficiaries' eligibility under the Access Plan until Dec. 31.

The letters contain the beneficiary's name, mailing address, Medical Care Plan number and co-pay percentage.

The government says the Office of the Information and Privacy Commissioner has been notified and it is working with an outside service provider to determine how the mistake was made to prevent it from happening again.
