when did canada and the us become allies
Canada–United States relations The Canadian military, like forces of other NATO countries, fought alongside the United States in most major conflicts since World War II, including the Korean War, the Gulf War, the Kosovo War, and most recently the war in Afghanistan. The main exceptions to this were the Canadian government's opposition to the Vietnam War and the Iraq War, which caused some brief diplomatic tensions. Despite these issues, military relations have remained close.
History of Canada Starting in the late 15th century, French and British expeditions explored, colonized, and fought over various places within North America in what constitutes present-day Canada. The colony of New France was established in 1534 and was ceded to the United Kingdom in 1763 after the French defeat in the Seven Years' War. The now British Province of Quebec was divided into Upper and Lower Canada in 1791 and reunified in 1841. In 1867, the Province of Canada was joined with two other British colonies of New Brunswick and Nova Scotia through Confederation, forming a self-governing entity named Canada. The new dominion expanded by incorporating other parts of British North America, finishing with Newfoundland and Labrador in 1949.
