VANCOUVER, British Columbia — Canada's game. Canada's ice. Canada's gold. Again. Marie-Philip Poulin scored two goals, Shannon Szabados made 28 saves, and Canada rolled through its American rivals, 2-0, to win the gold medal in women's hockey for the third straight Olympics Thursday night in front of a raucous Vancouver crowd ringing cowbells and frantically waving thousands of maple leaf flags. After Poulin's two first-period scores, the Canadians dominated every aspect of the biggest game in this young sport, earning their 15th straight Olympic victory. "I looked up in the stands and saw a sign that said, 'Proud to be Canadian,' and that's what I am today," Szabados said.
