One of the topics that attracts attention during the seventy-year history of establishing official relations between Iran and Canada (since 1956/1335) is the role of the book and its related issues in the relations between the two countries. According to the available documents, sending books from Iran to Canada by the government institutions and writing books about Iran (in Canada) with the cooperation and support of the Iranian government are the most important symbols of the connection between the two countries.  In this article, the role of the book in the framework of the official relations of the two countries from 1339 to 1357, has been investigated by using a descriptive-analytical method and relying on archival documents. The findings show that in this relatively short period, attention to the book on the political-cultural relations of the two countries has had significant importance and an expanding trend. In these publications, the history and culture of Iran have been written and published, and familiarity with Iran and the Persian language has expanded in Canada.
