Brad Gushue of Newfoundland and Labrador followed his opening draw win with a 8-3 victory over PEI, and is alone in first with a 2-0 record at the Tim Hortons Brier in Edmonton.
Manitoba's Jeff Stoughton stole a point in an extra end to beat Alberta's Kevin Martin 5-4 in a battle of curling heavyweights.
Manitoba, along with defending champion Glenn Howard of Ontario, Northern Ontario's Brad Jacobs, Saskatchewan's Brock Virtue and Quebec's Jean-Michel Menard are 1-0.
Ontario beat British Columbia 8-4 in the evening draw, while Jamie Koe's rink from the Territories defeated New Brunswick 10-7, and is 1-1.
Koe is keeping it simple, even after a breakout performance at the Canadian men's curling championship.
An historic result at the 2012 Tim Hortons Brier for his Territories team, with the added flourish of a Koe-versus-Koe playoff game, were entertaining storylines in Saskatoon.
Koe's Yellowknife team were the first Territories representative to make the playoffs at the Canadian championship since playoffs were introduced to the format in 1980.
The Koe foursome went 7-4 in the preliminary round, including an upset win over eventual Canadian champion Glenn Howard, to claim the fourth and final playoff berth.
Jamie Koe faced his brother Kevin's team from Alberta in the Page playoff between the third and fourth seeds. Jamie lost the playoff game to his younger brother and then the bronze medal game to Manitoba.
But for a region of the country that often struggles to be competitive at the Brier, finishing fourth among some of the best curling teams in Canada was significant.
Koe, third Tom Naugler, second Brad Chorostkowski and lead Robert Borden return to the Brier in Edmonton this year hoping to re-capture some of that magic from Saskatoon. Koe is skipping the Territories at the Brier for the seventh time in his career.
"I think we see ourselves as a middle-of-the-pack team," Koe said Saturday. "We're not going to make the playoffs every year, but the years we get hot, we think we'll be contention and that happened last year.
"We just have to give ourselves a chance this week, stick around the middle of the pack and try and set ourselves up for Friday to win a couple of games and get ourselves in the playoffs."
The top four teams at the conclusion of the round robin Friday make the playoffs.
