Northern Ontario and Quebec are the lone undefeated teams remaining at the Canadian Wheelchair Curling Championship.
The Gino Sonego rink swept both its games on Tuesday to improve to 4-0.
The Thunder Bay foursome downed Saskatchewan 7-2 in their opener, then only needed seven ends to drop Ontario 8-5 at the event, being staged in Ottawa.
The battle of the unbeatens will be front and centre Wednesday morning when Northern Ontario and Quebec tangle in Draw 5.
Sonego, lead Lola Graham, second Richard Dawid and third Doug Dean will take on New Brunswick (1-3) in the afternoon draw.
