Hi Samriti,
Your spouse can apply for the visa while you are applying for the student visa. Now, the question is your profile. Any good university will require work experience, GMAT score and higher percentile. Also, you already have done M.Com so universities will question you why an MBA now? First check with some universities and then apply. Also, keep alternate options like Australia, France, Netherlands, etc.

You should take IELTS.

Hi Dinakar Kuchi,
A majority of the universities require 75%. You will most likely find very few options in Canada. Check University of Alberta, McMaster University, University of Windsor, Dalhousie University, etc.

Hi Prerana, yes IELTS or TOEFL is generally required.

Hi Alvin, this mainly depend on the visa officer evaluating your profile but it's better not to take chance without IELTS in European countries. Also, it will hamper your job prospects later. Check with the school first if they can accept you without IELTS and you should prepare a strong application accordingly.
