A spokesman for the Ontario Lottery and Gaming Corp. says the ticket from the Dec. 30 draw was validated in the Ottawa area and officials have spoken to the ticket holders.
Tony Bitonti says no more information can be released until the two are confirmed to be the official winners.
They are expected at the Toronto prize centre this week.
There were also four winning $1-million MaxMillions numbers from the same draw.
Bitonti says one was sold in the Toronto area, and the three others in Western Canada.
