SOME PARTS OF CANADA "MISSING" GRAVITY ??

Yeah that's right.Apparently, some parts of Canada are missing gravity.
But if you think you can go there and levitate around, you're wrong.
Hudson bay and surrounding regions, including Quebec, have lower gravity the other parts of the world.That phenomenon is discovered in the 1960s when the Earth's gravity fields were being charted.So how much gravity is Canada "missing ? If you weigh 160 pounds you will be missing one tenth of an ounce. Not much, but it's interesting.There are several theories for this anomaly, one of them you can find here.
