Entrance requirements are program-specific, so you must check the exact program page. 

For high-school-entry programs: typically you need completion of Grade 12 (or equivalent) and required subject-courses (e.g., English, mathematics) as specified per program. 

For international students: official transcripts of secondary school, proof of English language proficiency (if English is not your first language). 

English language proficiency for all applicants: BCIT uses specific standards for English proficiency. 

Some programs at the Aerospace Technology Campus (e.g., Aircraft Maintenance Engineer) have additional entrance requirements such as tests or physical/medical requirements (for aviation-related safety programs).
