With the victory Canada sails into the knockout round with a ideal 3-0 mark sitting top of Group A followed by the U.S.at 2-1. Referees initially waved off the goal, but video review confirmed the puck crossed the goal line.
The United States skated away with the first gold in 1998 but Canada has reigned supreme ever since, winning four consecutive titles.
On Tuesday, a relentless Canada squad turned a pair of Finnish turnovers into a 2-0 first-period lead.
That means both teams get a spot directly in the tournament semi-finals and three days off before their next games while Finland, the Olympic Athletes from Russia, Switzerland and Sweden battle it out in the quarter-final round.
"You didn't really know what to expect it's been a long process we knew the Swiss would have a good and that they would play hard", Canada coach Willie Desjardins told reporters.

The front three fired heavily with Roberto Firmino also registering his name on the scoring sheet for his rampant side. Yacine Brahimi is the other attacking player helping Porto thrive offensively this season.
Daoust deftly delayed her pass to freeze the goalie and then slipped the puck between the defenceman's legs to Agosta for a tap-in goal just 35 seconds in.
"We've got great kids (nine rookies) and we've got great energy". The U.S. defeated the Olympic Athletes from Russian Federation 5-0 in the late game on Tuesday, securing semi-final berths for both Canada and the U.S. Canada was led in scoring by Daoust and Agosta, who each had one goal and one assist for two points.
Daoust finally gave Canada a 3-0 advantage in the second period, beating Raty with a wrister from the top of the right circle at 8:19. But officials upheld the no-goal call after review, without explanation. Since it became an Olympics sport, the two countries have fought relentlessly. "We're focused on the things that we can control, and certainly those games that we've played in the past have nothing to do with our future". However, Team USA will have to face the victor of the game between Switzerland and the fourth-place team in Group A. And considering how risky Alina Muller is, that's not a guaranteed win for Team USA. I think we might have got ahead of ourselves a little bit, maybe thinking too much offensively instead of playing a sound defensive game.
After a high-tempo scoreless opening period, Canada took control in the second on a power-play goal from Meghan Agosta and another from Sarah Nurse, who found the top corner of goalie Maddie Rooney's net with a laser-like wrist shot.
