According to Natural Resources Canada, the magnitude-5.6 earthquake struck just after noon, about 179 kilometres southwest of Tofino, B.C.
The federal agency also reported that it did not expect a tsunami.
Tofino Mayor Perry Schmunk says he was on the beach at the time and didn't feel a thing.
Schmunk says that's in direct contrast to a September 2011 magnitude-6.4 earthquake.
Just after that quake, Schmunk says the ground turned and he felt like he was standing on a waterbed.
