A magnitude-5.2 quake was recorded 90 kilometres southeast of Sandspit, on Haida Gwaii, around 4:30 a.m. on Sunday.
The U.S. National Oceanic and Atmospheric Administration says there was no tsunami danger from the quake.
A week ago a magnitude-7.7 quake struck off Haida Gwaii, prompting tsunami alerts along the B.C. coast and as far as Hawaii.
Nobody was hurt and the worst damage from that sizable shake-up was to turn off the taps of some natural hot springs.
There have been several aftershocks in the past week but none have caused any damage.
