The survival drama The Revenant, much of which was filmed in Alberta and B.C., took the top awards at this year's BAFTAs, including best film, actor and director.
The British Academy of Film and Television Arts awards are considered the British equivalent of the Academy Awards.
Leonardo DiCaprio won for his role of fur trapper Hugh Glass fighting for his life in The Revenant, which has also earned him his sixth Oscar nomination.
Alejandro Gonzalez Inarritu, who directed the notoriously-challenging epic, won best director.
Among the other winners, Brie Larson, who wasn't there, won best leading actress for her portrayal of a mother held captive in Room.
Kate Winslet won for her supporting role as Joanna Hoffman in the film Steve Jobs.
Mark Rylance won best supporting actor for the Steven Spielberg directed Cold War film Bridge of Spies.
Hundreds of fans gathered to watch the stars arrive at the Royal Opera House on a cool, crisp London evening.
Among the arrivals were nominees Mark Ruffalo, Michael Fassbender, Cate Blanchett, Saoirse Ronan, Steven Spielberg and the latest Star Wars hero John Boyega, who won the Rising Star award.
Like Hollywood's Academy of Motion Picture Arts and Sciences, the British film academy says it will work to make sure its 6,500 voting members become a more diverse group.
On the red carpet, Boyega said he was glad the issue was being aired. "I just think a larger conversation is being had and I think that's a very, very positive thing," he said.
