All the best

Dear Rajan,
There is no official ranking system followed by Canadian universities. Among the top most you have McGill, University of Toronto, University of British Columbia, University of Waterloo and Queens University.

Hi,
It would be difficult to get admission with this percentage but if you have good IELTS/TOEFL score, it might help you.

Dear Mani, aim for an upper first class which can be above 70%. Canadian universities are quite selective.

Dear Amritpal, how about a Bachelor of business administration or business management, you can also consider Bachelor of commerce at the first place but must cope with economics classes. Another good choice could be CA,CPA, CIMA,CMA etc. You can plan for a Masters in finance in future. Please remember that for a successful career in finance you must have a knack for economics and its ups and downs.
Best Wishes
