James Bay (, ) is a large body of water on the southern end of
Hudson Bay in
Canada. Both bodies of water extend from the
Arctic Ocean. It is the southernmost part of the Arctic Ocean. James Bay borders the provinces of
Quebec and
Ontario; islands within the bay (the largest of which is
Akimiski Island) are part of
Nunavut. The James Bay watershed is the site of several major
hydroelectric projects, and is also a destination for river-based recreation. Several communities are located near or alongside James Bay, including a number of
Aboriginal communities such as the
Kashechewan First Nation and nine communities affiliated with the
Crees of northern Quebec.
