Ontario Lottery and Gaming is pulling more than 1 million scratch tickets from stores because of a security concern, CTV News has learned.

"Super Bingo," the lottery corporation's most popular scratch-and-win game, has been ordered removed from the province's 10,000 retailers after a player complained that winners could be picked without having to scratch the ticket.

The concerned citizen contacted the Ontario ombudsman's office, which is currently investigating allegations of fraudulent wins.

The so-called method of picking winners is not yet clear.

While there is no evidence the complainant's claim is in fact true, OLG is deciding to "err on the side of caution," CTV's Paul Bliss reported.

OLG has posted an alert to players on its website.

Two versions of the cards have been recalled. They are:

  • Super Bingo Game #1074, released in November; and
  • Super Bingo Game #1076, released in January.

Retailers have been rushed a replacement Super Bingo game called "Hawaiian Bingo."

Ombudsman Andre Marin launched an investigation last fall after allegations that lottery-ticket retailers have won too many large prizes over the last seven years.

OLG has stepped up security measures following the allegations, including customer-facing video screens at lottery terminal locations.

Marin is expected to release his report in about a month.
