An IELTS score of 6.5 is a decent score, but I am not very sure of what you mean by an aggregate score of 7.0. Is it the overall IELTS band scale you are referring to or your Engineering/ Graduation CGPA/ SGPA. However, whatever be the case, IELTS as the name suggests is an examination for International English Language Testing System. It is conducted purely to test your language skills in the four modules I. e. listening, reading, writing and speaking. No university, not just in Canada, but in the entire world will provide you scholarship based only on your IELTS score. The scholarships provided by the universities to any student are based on a number of factors rather than mere one or two assessing criteria. As far as my knowledge is concerned, students are granted financial aids/ scholarships based on a combined profile of their -
10th & 12th examination marks
Undergraduate degree performance [if applying for a master's programme]
Test results for the courses applied to [I. e. IELTS/ GRE/ GMAT and
The statement of Intent / the Scholarship essay drafted by the student. Once you are assessed on the above criteria and the university feels that you stand out among the other candidates who applied for the same grant, you might be awarded partial or complete funding as per the university norms/ rules and regulations.
