Apostille for Canadian Ontario Secondary School Diploma (OSSD) – International Schools

The Ontario Secondary School Diploma (OSSD) is one of the world’s most respected high school qualifications. Originating in Canada, the OSSD has become increasingly popular across international schools, including bilingual, private, and global education campuses worldwide. With a flexible curriculum, credit-based progress system, and strong university recognition, the OSSD provides pathways into higher education in Canada, the United States, the UK, Switzerland, Australia, and beyond (Apostille for Ontario Secondary School Diploma).

Despite its widespread acceptance, many universities, scholarship bodies, and national authorities require proof that the diploma is officially recognised before they will process an application. For international study, work, or immigration, the OSSD frequently needs to be apostilled to validate its authenticity.

An apostille is a government-issued certification confirming that a document is genuine, legally valid, and recognised abroad. This validation is required by all countries that participate in the Hague Apostille Convention and is essential when presenting academic qualifications outside Switzerland. Without an apostille, even well-known certificates like the OSSD may be rejected or delayed.
