The Russians, with their teenage ice starlets Evgenia Medvedeva and Alina Zagitova, took their first silver of the Games. The USA team was third.
The Canadian team, also featuring dual 2014 silver medallist Patrick Chan, fulfilled their promise as favourites to beat Olympic Athletes from Russia, after comming second to Russia four years ago in Sochi.
They took command on Friday, despite Chan tumbling in his men's short programme.
Competing in their third Olympics, Virtue and Moir earned a maximum 10 points for their short programme, and matched that in the concluding free with an exhilarating four-and-a- half minute performance to the music of Moulin Rouge.
Canada finished on 73 points, with OAR on 66 and the USA a further four points behind.
And they didn't let them down at the Gangneung Ice Arena.
For defending champions Russia, competing in South Korea as OAR after Russia's state-sponsored doping ban, it was always going to be a struggle to recover from Mikhail Kolyada's flop in the men's short programme.
Medvedeva conjured up a world record score in Sunday's short programme, with Zagitova producing a personal best in her free dance to Don Quixote.
The pair are heading for a mouthwatering showdown for the women's title next week.
As for the men, US quad boy wonder Nathan Chen, rated one of the Japanese skating icon's main dangers, will be working overtime in training after making mistakes in his short routine.
Hanyu sat out the team competition as he gave his body every chance of being at its best for the defence of his crown after ankle ligament damage threatened to scuttle his Olympic dream last November.
He is due to train for the first time since arriving in Pyeongchang later today.
