Does Canada Have a Low Gravity Spot?

There is a spot in Canada that has less gravity than the rest of the
planet.

Canada has a low gravity spot, which researchers believe might be due in
part to residual effects of heavy glaciers during the Ice Age. It is
thought that the weight of the glaciers pressed down on the Earth’s crust
in the area that is now northern Canada and left an impression that is
still in the process of rebounding. Although the gravity levels continue to
slowly increase at a rate of about 0.5 inches (1 cm) each year, the area
has minimally less gravity — 0.1 ounces (2.8 g) for a 150-pound (68 kg)
person — than the rest of the Earth. Scientists also believe that rocks
in the Earth’s crust might be being pulled downward at the low gravity
spot, contributing to the effect.
