1965 International Co-operation Year

On November 21, 1963, the General Assembly of the United Nations adopted a resolution whereby the year 1965, the twentieth year of the establishment of the United Nations, would be designated as International Co-operation Year. The Assembly called upon all member countries to publicize the activities of international co-operation in which they were engaged and to draw up plans to promote the objectives of International Co-operation Year. Canada was a member of the preparatory committee for this project and a member of the United Nations Committee for I.C.Y.
The Canada Post Office marked the achievements of international co-operation with a slogan cancellation and the release of the I.C.Y. stamp on March 3, 1965. The stamp was designed by Harvey Thomas Prosser.
