People in coastal areas of Haida Gwaii were reportedly being moved to higher ground as a precaution, Kazinform has learnt from BBC.
Urs Thomas, operator of the Golden Spruce hotel in Port Clements, close to the epicentre, said the initial quake lasted about three minutes.
"It was a pretty good shock," he told Associated Press. "I looked at my boat outside. It was rocking. Everything was moving. My truck was moving."
Prince Rupert resident Grainne Barthe told AP: "Everything was moving. It was crazy. I've felt earthquakes before but this was the biggest. It was nerve wracking. I thought we should be going under a table."
