The 4.5-magnitude quake occurred at 5:41 Monday morning and was centred about three kilometres below the surface, roughly 70 kilometres southwest of Sandspit.
Natural Resources Canada says it was not strong enough to cause any damage or spawn a tsunami.
A 4.3 magnitude shaker was recorded in roughly the same area on Sunday morning but officials say no reports of damage were received, and none would be expected.
The two events are among hundreds of earthquakes that have occurred recently along the Pacific Coast, the most earthquake-prone region of Canada
A 7.7 magnitude earthquake rocked Haida Gwaii in October, the strongest quake recorded in Canada since an 8.1 shaker hit the same area in 1949.
