In 1759, after winning the Battle of the Plains of Abraham, Britain took control of the colony of New France. After this, British North America also included New France.
After the American Revolution, some people still used the term to refer to what is now the country of Canada. In fact, the Canadian Constitution was first called the "British North America Act 1867" (which first became a law in 1867).
