Relationship Between USAd Canada

December 24, 1814, marked the end of “the War of 1812” having a treaty signed that returned all territorial conquest made by the two sides, Canada and the U.S. The two nations have remained peaceful ever since. The two nations share a relationship that is seen as strong, vigorous and substantial. With the relationship having spanned for more than two centuries, they share the world's longest undefended border and have been beneficial to the economies of both nations. However, this relationship has only gotten stronger.The relationship between the U.S. and Canada has changed for the better through the strengthened economy/trade flow, their shared concerns for the ever so diminishing environment, and in Canada's assistance with the war in Afghanistan.
The U.S. and Canada have a history of effective cooperation on water related environmental issues having over 300 lakes and rivers flow across, or lie along the borders of Canada and U.S. The International Joint Commission, was created due to the fact that each country is affected by the others actions along the border. Over a century later, both Canada and U.S.. continue to preserve both the quality and quantity of the boundary waters shared between the two nations, including the spread of invasive species like the zebra mussels and the Asian Carp. Canada along with the U.S. have a long history of effective cooperation to enhance the air quality . Canada and the U.S.signed the Air Quality Agreement (AQA) in 1991, its purpose was to set specific air quality objectives and the reduction of acid rain.The signing of the Ozone Annex to the AQA in December 2000 was because of the shared desire to continue working together to enhance air quality. The Annex benefits millions of citizens from Canada and the U.S. by significantly reducing transboundary flows of the air pollutants that cause smog.. The shared concept of improving the continent to be a safer, healthier place for their people and future generations to reside in have made the relationship between the two nations
An event so catastrophic, that is still remembered up to this day. On September 11, 2001, Al Qaeda extremists carried out suicide attacks on the World Trade Centre killing over 3,000 Americans. This then resulted in the Afghan mission as Americans launched a NATO-sanctioned invasion of Afghan on October 7, 2001 in an effort to capture Osama Bin Laden and to expel the Taliban power in Kabul. Canada then joined the mission in 2001, deploying a 40 person commando unit to Kabul. By 2002, Canadian military commitment increased the amount of troops to 1900 based outside of Kabul as they worked closely with the Americans. By 2006, over 2,300 soldiers would be stationed in Afghanistan as they moved to the southern part of the country engaging in heavy combat against Taliban. By July 2011, 157 troops have died, the mission then began to take a heavy toll on Canada as the mission costed them about $18.5 billion, resulting in the end of the mission in July 2011. However, approximately 1,000 soldiers have remained in Afghanistan tasked with helping US and other NATO forces in training the Afghan national Army. With Canada being a close ally to the United States, they have yet again shown that the two militaries are capable of fighting side by side. Canada was ready to share common burdens with its ally. This shows the true bond between the two nations as yet again their relation strengthened as a
