History


Colonial wars

Before the British conquest of French Canada in 1760, there had been a series of wars between the British and the French which were fought out in the colonies as well as in Europe and the high seas. In general, the British heavily relied on American colonial militia units, while the French heavily relied on their First Nation allies. The Iroquois Nation were important allies of the British. Much of the fighting involved ambushes and small-scale warfare in the villages along the border between New England and Quebec. The New England colonies had a much larger population than Quebec, so major invasions came from south to north. The First Nation allies, only loosely controlled by the French, repeatedly raided New England villages to kidnap women and children, and torture and kill the men. Those who survived were brought up as Francophone Catholics. The tension along the border was exacerbated by religion, the French Catholics and English Protestants had a deep mutual distrust. There was a naval dimension as well, involving

Britain advised the French Canadians that the British Empire already enshrined their rights in the Quebec Act, which the American colonies had viewed as one of the Intolerable Acts. The American invasion was a fiasco and Britain tightened its grip on its northern possessions; in 1777, a major British invasion into New York led to the surrender of the entire British army at Saratoga, and led France to enter the war as an ally of the U.S. The French Canadians largely ignored France's appeals for solidarity. After the war Canada became a refuge for about 75,000 Loyalists who either wanted to leave the U.S., or were compelled by Patriot reprisals to do so. Among the original Loyalists there were 3,500 free African Americans. Most went to Nova Scotia and in 1792, 1200 migrated to

churches. In later years, Anglophone Canadians, especially in Ontario, viewed the War of 1812 as a heroic and successful resistance against invasion and as a victory that defined them as a people. The myth that the Canadian militia had defeated the invasion almost single-handed, known logically as the "militia myth", became highly prevalent after the war, having been propounded by John Strachan, Anglican Bishop of York.


Post War of 1812 and mid-19th century

In the aftermath of the War of 1812, pro-British conservatives led by Anglican Bishop John Strachan took control in Ontario ("Upper Canada"), and promoted the Anglican religion as opposed to the more republican Methodist and Baptist churches. A small interlocking elite, known as the Family Compact took full political control. Democracy, as practiced in the US, was ridiculed. The policies had the desired effect of deterring immigration from United States. Revolts in favor of democracy in Ontario and Quebec ("Lower Canada") in 1837 were suppressed; many of the leaders fled to the US. The American policy was to largely ignore the rebellions, and indeed ignore Canada generally in favor of westward expansion of the American Frontier. The Webster-Ashburton Treaty formalized the U.S.-Canada border in Maine, averting the Aroostook War. During the

They raided the town St. Albans, Vermont on October 19, 1864, killing an American citizen and robbing three banks of over US$200,000. The three Confederates escaped to Canada where they were arrested, but then released. Many Americans suspected – falsely – that the Canadian government knew of the raid ahead of time. There was widespread anger when the raiders were released by a local court in Canada. The American Secretary of State William H. Seward let the British government know, "it is impossible to consider those proceedings as either legal, just or friendly towards the United States."

None of these raids achieved their aims and all were quickly defeated by local Canadian forces.

Early 20th century


Alaska boundary

A short-lived controversy was the Alaska boundary dispute, settled in favor of the United States in 1903. The issue was unimportant until the Klondike Gold Rush brought tens of thousands of men to Canada's Yukon, and they had to arrive through American ports. Canada needed its port and claimed that it had a legal right to a port near the present American town of

, Alaska. It would provide an all-Canadian route to the rich goldfields. The dispute was settled by arbitration, and the British delegate voted with the Americans—to the astonishment and disgust of Canadians who suddenly realized that Britain considered its relations with the United States paramount compared to those with Canada. The arbitration validated the status quo, but made Canada angry at London. 1907 saw a minor controversy over USS ''Nashville'' sailing into the Great Lakes via Canada without Canadian permission. To head off future embarrassments, in 1909 the two sides signed the International Boundary Waters Treaty and the

treaty with the U.S. that would lower trade barriers. Canadian manufacturing interests were alarmed that free trade would allow the bigger and more efficient American factories to take their markets. The Conservatives made it a central campaign issue in the 1911 election, warning that it would be a "sell out" to the United States with economic annexation a special danger. The Conservative slogan was "No truck or trade with the Yankees", as they appealed to Canadian nationalism and nostalgia for the British Empire to win a major victory.


World War I

British Canadians were annoyed in 1914-16 when Washington insisted on neutrality and seemed to profit heavily while Canada was sacrificing its wealth and its youth. However when the US finally declared war on Germany in April 1917, there was swift cooperation and friendly coordination, as one historian reports:
Official co-operation between Canada and the United States—the pooling of grain, fuel, power, and transportation resources, the underwriting of a Canadian loan by bankers of New York—produced a good effect on the public mind. Canadian recruiting detachments were welcomed in the United States, while a reciprocal agreement was ratified to facilitate the return of draft-evaders. A Canadian War Mission was established at Washington, and many other ways the activities of the two countries were coordinated for efficiency. Immigration regulations were relaxed and thousands of American farmhands crossed the border to assist in harvesting the Canadian crops. Officially and publicly, at least, the two nations were on better terms than ever before in their history, and on the American side this attitude extended through almost all classes of society.


Post-First World War

Canada demanded and received permission from London to send its own delegation to the Versailles Peace Talks in 1919, with the proviso that it sign the treaty under the British Empire. Canada subsequently took responsibility for its own foreign and military affairs in the 1920s. Its first ambassador to the United States,

was unveiled in Stanley Park in 1925. Relations with the United States were cordial until 1930, when Canada vehemently protested the new Smoot–Hawley Tariff Act by which the U.S. raised tariffs (taxes) on products imported from Canada. Canada retaliated with higher tariffs of its own against American products, and moved toward more trade within the British Commonwealth. U.S.–Canadian trade fell 75% as the Great Depression dragged both countries down. Down to the 1920s the war and naval departments of both nations designed hypothetical war game scenarios on paper with the other as an enemy. These were routine training exercises; the departments were never told to get ready for a real war. In 1921, Canada developed Defence Scheme No. 1 for an attack on American cities and for forestalling invasion by the United States until British reinforcements arrived.

Later however, Chrétien publicly mused that U.S. foreign policy might be part of the "root causes" of terrorism. Some Americans criticized his "smug moralism", and Chrétien's public refusal to support the 2003 Iraq war was met with negative responses in the United States, especially among conservatives.

On December 7, 2011, Harper flew to Washington, met with Obama and signed an agreement to implement the joint action plans that had been developed since the initial meeting in February. The plans called on both countries to spend more on border infrastructure, share more information on people who cross the border, and acknowledge more of each other's safety and security inspection on third-country traffic. An editorial in ''The Globe and Mail'' praised the agreement for giving Canada the ability to track whether failed refugee claimants have left Canada via the U.S. and for eliminating "duplicated baggage screenings on connecting flights". The agreement is not a legally binding treaty, and relies on the political will and ability of the executives of both governments to implement the terms of the agreement. These types of executive agreements are routine—on both sides of the Canada–U.S. border.

Moreover, interoperability with the American armed forces has been a guiding principle of Canadian military force structuring and doctrine since the end of the Cold War. Canadian navy frigates, for instance, integrate seamlessly into American carrier battle groups. In commemoration of the 200th Anniversary of the War of 1812 ambassadors from Canada and the US, and naval officers from both countries gathered at the Pritzker Military Library on August 17, 2012, for a panel discussion on Canada-US relations with emphasis on national security-related matters.

to resolve differences and promote international cooperation on boundary waters. The Great Lakes Water Quality Agreement of 1972 is another historic example of joint cooperation in controlling trans-border water pollution. However, there have been some disputes. Most recently, the Devil's Lake Outlet, a project instituted by North Dakota, has angered Manitobans who fear that their water may soon become polluted as a result of this project. Beginning in 1986, the Canadian government of Brian Mulroney began pressing the Reagan administration for an "Acid Rain Treaty" in order to do something about U.S. industrial air pollution causing acid rain in Canada. The Reagan administration was hesitant, and questioned the science behind Mulroney's claims. However, Mulroney was able to prevail. The product was the signing and ratification of the

Newfoundland fisheries dispute

The United States and Britain had a long-standing dispute about the rights of Americans fishing in the waters near Newfoundland. Before 1776, there was no question that American fishermen, mostly from Massachusetts, had rights to use the waters off Newfoundland. In the peace treaty negotiations of 1783, the Americans insisted on a statement of these rights. However, France, an American ally, disputed the American position because France had its own specified rights in the area and wanted them to be exclusive. The

gave the Americans not rights, but rather "liberties" to fish within the territorial waters of British North America and to dry fish on certain coasts. After the War of 1812, the Convention of 1818 between the United States and Britain specified exactly what liberties were involved. Canadian and Newfoundland fishermen contested these liberties in the 1830s and 1840s. The Canadian–American Reciprocity Treaty of 1854, and the Treaty of Washington of 1871 spelled-out the liberties in more detail. However the Treaty of Washington expired in 1885, and there was a continuous round of disputes over jurisdictions and liberties. Britain and the United States sent the issue to the Permanent Court of Arbitration in The Hague in 1909. It produced a compromise settlement that permanently ended the problems.

in 1985, which actually resulted in a minor diplomatic incident. In 1970, the Canadian parliament enacted the Arctic Waters Pollution Prevention Act, which asserts Canadian regulatory control over pollution within a 100-mile zone. In response, the United States in 1970 stated, "We cannot accept the assertion of a Canadian claim that the Arctic waters are internal waters of Canada.... Such acceptance would jeopardize the freedom of navigation essential for United States naval activities worldwide." A compromise of sorts was reached in 1988, by an agreement on "Arctic Cooperation," which pledges that voyages of American icebreakers "will be undertaken with the consent of the Government of Canada." However the agreement did not alter either country's basic legal position.

Views of presidents and prime ministers

Presidents and prime ministers typically make formal or informal statements that indicate the diplomatic policy of their administration. Diplomats and journalists at the time—and historians since—dissect the nuances and tone to detect the warmth or coolness of the relationship. * Prime Minister
John A. Macdonald Sir John Alexander Macdonald (January 10 or 11, 1815 – June 6, 1891) was the first prime minister of Canada, serving from 1867 to 1873 and from 1878 to 1891. The dominant figure of Canadian Confederation, he had a political career that sp ...
, speaking at the beginning of the 1891 election (fought mostly over Canadian free trade with the United States), arguing against closer trade relations with the U.S. stated "As for myself, my course is clear. A British subject I was born—a British subject I will die. With my utmost effort, with my latest breath, will I oppose the ‘veiled treason’ which attempts by sordid means and mercenary proffers to lure our people from their allegiance." (February 3, 1891.) Canada's first Prime Minister also said: * Prime Minister John Sparrow Thompson, angry at failed trade talks in 1888, privately complained to his wife, Lady Thompson, that "These Yankee politicians are the lowest race of thieves in existence." * After the World War II years of close military and economic cooperation, President Harry S. Truman said in 1947 that "Canada and the United States have reached the point where we can no longer think of each other as 'foreign' countries." * President John F. Kennedy told Parliament in Ottawa in May 1961 that "Geography has made us neighbors. History has made us friends. Economics has made us partners. And necessity has made us allies. Those whom nature hath so joined together, let no man put asunder." * President Lyndon Johnson helped open Expo '67 with an upbeat theme, saying that "We of the United States consider ourselves blessed. We have much to give thanks for. But the gift of providence we cherish most is that we were given as our neighbours on this wonderful continent the people and the nation of Canada." Remarks at Expo '67, Montreal, May 25, 1967. * Prime Minister Pierre Elliot Trudeau famously said that being America's neighbour "is like sleeping with an elephant.

Anti-Americanism

Since the arrival of the Loyalists as refugees from the American Revolution in the 1780s, historians have identified a constant theme of Canadian fear of the United States and of " Americanization" or a cultural takeover. In the War of 1812, for example, the enthusiastic response by French militia to defend Lower Canada reflected, according to Heidler and Heidler (2004), "the fear of Americanization." Scholars have traced this attitude over time in Ontario and Quebec. Canadian intellectuals who wrote about the U.S. in the first half of the 20th century identified America as the world center of modernity, and deplored it. Anti-American Canadians (who admired the British Empire) explained that Canada had narrowly escaped American conquest with its rejection of tradition, its worship of "progress" and technology, and its mass culture; they explained that Canada was much better because of its commitment to orderly government and societal harmony. There were a few ardent defenders of the nation to the south, notably liberal and socialist intellectuals such as F. R. Scott and Jean-Charles Harvey (1891–1967). Looking at television, Collins (1990) finds that it is in Anglophone Canada that fear of cultural Americanization is most powerful, for there the attractions of the U.S. are strongest. Meren (2009) argues that after 1945, the emergence of Quebec nationalism and the desire to preserve French-Canadian cultural heritage led to growing anxiety regarding American cultural imperialism and Americanization. In 2006 surveys showed that 60 percent of Québécois had a fear of Americanization, while other surveys showed they preferred their current situation to that of the Americans in the realms of health care, quality of life as seniors, environmental quality, poverty, educational system, racism and standard of living. While agreeing that job opportunities are greater in America, 89 percent disagreed with the notion that they would rather be in the United States, and they were more likely to feel closer to English Canadians than to Americans.Paula Ruth Gilbert, ''Violence and the Female Imagination: Quebec's Women Writers'' (2006) p. 114 However, there is evidence that the elites and Quebec are much less fearful of Americanization, and much more open to economic integration than the general public. The history has been traced in detail by a leading Canadian historian J.L. Granatstein in ''Yankee Go Home: Canadians and Anti-Americanism'' (1997). Current studies report the phenomenon persists. Two scholars report, "Anti-Americanism is alive and well in Canada today, strengthened by, among other things, disputes related to NAFTA, American involvement in the Middle East, and the ever-increasing Americanization of Canadian culture." Jamie Glazov writes, "More than anything else, Diefenbaker became the tragic victim of Canadian anti-Americanism, a sentiment the prime minister had fully embraced by 1962. e wasunable to imagine himself (or his foreign policy) without enemies." Historian J. M. Bumsted says, "In its most extreme form, Canadian suspicion of the United States has led to outbreaks of overt anti-Americanism, usually spilling over against American residents in Canada." John R. Wennersten writes, "But at the heart of Canadian anti-Americanism lies a cultural bitterness that takes an American expatriate unaware. Canadians fear the American media's influence on their culture and talk critically about how Americans are exporting a culture of violence in its television programming and movies." However Kim Nossal points out that the Canadian variety is much milder than anti-Americanism in some other countries. By contrast Americans show very little knowledge or interest one way or the other regarding Canadian affairs. Canadian historian Frank Underhill, quoting Canadian playwright
