After the Seven Years' War ended in 1763 handing over of New France to the British, the citizens of Halifax held a special day of Thanksgiving. Thanksgiving days were observed beginning in 1799 but did not occur every year. After the American Revolution, American refugees who remained loyal to Great Britain moved from the newly independent United States and came to Canada. They brought the customs and practices of the American Thanksgiving to Canada. The first Thanksgiving Day after Canadian Confederation was observed as a civic holiday on April 5, 1872 to celebrate the recovery of the Prince of Wales (later King Edward VII) from a serious illness.
