Perhaps the most widely used English language test in the world is the International English Language Testing System (IELTS), which is frequently tied with the Test of English as a Foreign Language (TOEFL). Similar to CELPIP, it comes in two flavours: general and academic. Candidates would need to take the IELTS General exam in order for Citizenship and Immigration Canada (CIC) to recognise their IELTS scores. IELTS Academic is not acceptable for immigration because it is designed for students rather than immigrants who aren't already enrolled in school.
