Hello,
As per the checklist of study permit from India. It is Highly Recommended to submit English language proficiency test score.
But, This varies case by case. I have some friends who have been selected for masters in canada without IELTS (or toefl) requirement. (they have exempted some universities in India as they have mutual tie-ups with this university) Now they have applied for visa without IELTS, but with a letter form current university stating that English is the language of instruction. I am also waiting for their decision (out of curiosity). One has applied on 30 jun and other on 8th july. I will post here once I hear from them about their decision.
Btw If I were you I wouldn't take a risk for applying without IELTS, or toefl. God forbid, If you get a rejection, you might not get the funding for deferral to jan intake.
