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.

If you are planning to study abroad, the admission process will require you to give one language exam and one standardized exam. However, depending on the country, course or college you are targeting, you may be exempt from standardized exams, but you would still be required to take one language exam to show English language proficiency. Depending on the course and college, you may also be required to provide scores of one standardized test. Looking for Abroad Counselling?

Hi,GRE Graduate Record Examination:
GRE is the most commonly required standardized admission test for the students who would like to take an admission in a graduation school to study abroad. Just like SAT and ACT, GRE consist of topics like, analytical writing, quantitative analysis and verbal reasoning. These are the skills the students develop over the years, and many universities worldwide will assess the GRE scores as an eligibility criterion for their admission process, since 1949.
There are two types of GRE exam:
GRE General Test:
GRE general test is a more comprehensive assessment of candidate's quantitative and reasoning abilities. It is the most commonly taken test type of GRE. It either can be just for the admission formality, or for the merit based admission in a particular course for Master of Science (MS) or Master of Business Administration (MBA).
GRE Subject Test:
GRE Subject Test, as the name suggest, is taken by the students who want to make their application stand out in a particular subject, and have an edge for a particular score. A GRE subject test shows the candidates skills for a particular field of specialization, and therefore it is useful to the students who already have a Bachelor's degree and want to go ahead with a particular subject.
