I graduated from an English-or French-language high school/college/university. What can I use to show that I can communicate in one of the official languages when I apply for citizenship?

You may send a transcript, diploma or certificate showing that you graduated from a secondary school or from a post-secondary program in Canada or abroad. These materials must show that the program was in English or French. A single course in an official language is not enough to meet this requirement.
