Accounting & Commerce

Hi Abhishek,
You must decide this yourself. Canada being a finance center of the world, a B.Com and CPA will be more beneficial provided you have the interest and passion for finance, accounts, etc. If you are interested for a finance career then this is the course you should opt.
Students in the accounting and financial management (AFM), Biotechnology/CPA, and mathematics/CPA programs can combine their undergraduate studies with the Master of accounting (MAcc) graduate program to move directly to the CPA common final examination (CFE) after graduation.
Similarly, go through the BBA/BCS program and check the curriculum and decide which fits your interest and aim/goals.

ACCA is indeed a good certification globally. But, in Indian context, it is still struggling to be relevant primarily because of already established professional certifications like CA and CMA. ACCA provides good exposure in globally relevant areas like IFRS and US GAAP. But again, in India ACCA doesn't have strong base compared to its local counter parts. A local degree course such as MBA along with ACCA can be a good combination in India.
This is my personal opinion. You may research further or take an advice from a qualified ACCA regarding the scenario in India.
CIMA certification will give you a overall knowledge of accounting as this is course is focused on management term you'll be able to answer the whys and whats of the accounts and actually provide a way forward. Management accounting is basically accounting for internal affairs, making decisions related to product, cost, time which affects business outcome. CIMA certification enhances your professional stature and opens up the opportunity to work with imminent clients and depicts that you are committed to increase your knowledge by studying further.
Pursuing CIMA doesn't put you at risk of losing your money for a long time. MBA does. The fees is affordable, the course is comprehensive (without fluff) and the subjects covered in the course are relevant.
