After migrating from the East Coast in ancient times, they settled on Manitoulin Island, near the northern shores of Lake Huron, and the Bruce Peninsula in the present-day province of Ontario, Canada. They considered this their original homeland. After the 17th century, they also settled along the Ottawa River, and in the present-day states of Michigan and Wisconsin, as well as through the Midwest south of the Great Lakes in what became the United States. In the 21st century, there are approximately 15,000 Odawa living in Ontario, and Michigan and Oklahoma (former Indian Territory, United States).
