International students can apply to ÉTS through the university's online application portal. In addition to meeting the general admission requirements, international applicants must provide official transcripts evaluated by a recognized credential assessment organization to ensure equivalency with Canadian education standards. Proof of French language proficiency is mandatory, which may involve submitting results from standardized tests like the TFI (Test de français international) or demonstrating completion of prior education in French. Applicants are also required to submit a valid passport copy and may need to provide proof of financial capability to cover tuition and living expenses. It's advisable to begin the application process well in advance to accommodate processing times for visas and other necessary documentation.

The admission process at ÉTS follows a structured timeline. Application deadlines vary depending on the program and whether the applicant is a domestic or international student. Generally, for the fall semester beginning in September, applications should be submitted by March, while for the winter semester starting in January, the deadline is typically in September. After submission, the evaluation process may take several weeks, during which applicants' academic credentials and supporting documents are reviewed. Accepted students will receive an official offer of admission, after which they should proceed with securing immigration documents, arranging housing, and preparing for enrollment. It's crucial to adhere to the specified deadlines and regularly check the application portal for updates.
