Hi Sabiq. It is difficult to study overseas especially in countries like Canada without IELTS. For student Visa, one needs to score 6.5 ,not less than 6 bands in any . But there is one way to study abroad,  one can apply for student exchange program through one's university / college (if your university/college offers foreign exchange program) . But if your institution doesn't do that, then without IELTS.

Also, IELTS is not valid everywhere. It is valid in canada, Australia and some parts of US. There are different exams for different countries.
