Canadians travelling to Turkey for tourism or trade can purchase an electronic visa prior to entering the country. This visa replaces the “sticker” and “stamp-type” visas issued at Turkish points of entry. If you are planning on studying or working in Turkey, you must obtain a visa at a Turkish embassy or consulate.
