Country comparison
British-Canadian relations are the relations between Canada and the United Kingdom of Great Britain and Northern Ireland, being bilateral relations between their governments and wider relations between the 2 societies. The two countries have intimate and frequently cooperative contact; they are related through mutual migration, through shared military history, through a shared system of government, through language, through the Commonwealth of Nations, and their sharing of the same Head of State and monarch. Despite this shared legacy, the two nations have grown apart economically and politically: Britain has not been Canada's largest trading partner since the nineteenth century. Currently Canada and Britain are in different trade blocs, such as NAFTA and the European Union respectively, as well as Britain's independent trade negotiations due to its process of leaving the EU after Brexit. Nonetheless, the two share a defence agreement, NATO and frequently perform military exercises together with Canada hosting the largest British Military Base outside the United Kingdom.
