OLG officials say the person who bought a Lotto 6/49 ticket in Chatham that is worth $6.1-million has yet to claim their prize.
However, the person who bought the ticket knows they are a winner because the ticket has been validated.
An OLG spokesperson says it's not uncommon for someone to check their ticket and then wait a while to claim their winnings, especially for the big money prizes.
Players have one year from the original draw date to claim their prize.
Officials say they cannot disclose where the ticket was purchased -- or who purchased it -- until after it has been claimed at the OLG Prize Centre in Toronto.
One of two winning tickets for the September 20, 2017 Lotto 6/49 draw was sold in Chatham. The other winning ticket was sold in Quebec.
Each of the winners will take home $6.1-million.
