Earlier this month it was noted that the Canadian High Commission in the UK had been established 137 years ago. However, this 'reluctant consent' to permit the establishment of a Canadian High Commission in London didn't allow for full diplomatic autonomy: Until the early 1900's Great Britain was responsible for Canada's International Affairs.
On June 9th 1909, the Department of External Affairs opened, but Canada's diplomatic presence abroad did not start until after World War I. However, by 1930 Canada had diplomatic posts in Paris, Geneva, Tokyo, and Washington DC, and by 1945 was one of the founding members of the United Nations.
Canada has matured extremely well over the past 150 years: starting as a collection of colonies gaining independence to a member of the G7. Let us imagine the progress it will have made by its 300th anniversary!
