Canada's shutout streak ended midway through the third period, but that was the only hiccup as the four-time defending women's hockey gold medalist dispatched yet another opponent with a 4-1 win over Finland early Tuesday morning.

Meghan Agosta and Melodie Daoust led the way with a goal and an assist each.

The win put Canada atop Group A and virtually guaranteed advancement to the semifinals.

Agosta opened the scoring just 35 seconds into the game, before Sochi 2014 hero and team captain Marie-Philip Poulin roofed her first goal of the tournament on a beauty deke:

Canada went up 3-0 in the second frame on a point shot from Daoust. Jillian Saulnier then became the first Nova Scotian to score a goal in Olympic women's hockey when her breakaway tally extended the lead to 4-0.

Canada's dominance let up a little in the third period, as Finland claimed a goal when 44-year-old Riikka Valila became the oldest woman to ever score at the Olympics.

Finland then nearly added another on a breakaway, but Canadian netminder Shannon Szabados stood tall to keep the lead at three.

Canada will close out the group stage with a game against its bitter rival, the United States, on Thursday.
