Dear, first of all I would like to suggest you is that, you should listen to yourself, there should be a correlation between your mind and heart. I f you listen to yourself, you will choose the subjects of your choice, definitely you will do better. If some one impose their choice on you, and you carry their choice, you will perform but not up to the mark, reason being that you are not doing or pursuing that thing or course at your own will. Results will be poor performance or results.

Let me come to another question of going to Canada. Canada is big country and has many opportunities for majority and diversified subjects. You are interested in finance management and Human resource management (HRM) and your brother is forcing or suggesting you for business management . In my opinion Finance Management is better choice. The reasons being that in private sector, the finance companies they recruit finance manager or financial persons. The finance person plays a very crucial role in any organization. The job is respectable, gives job satisfaction and chances of growth are more.
If we discuss about government organization, if you have the masters and doctoral degree in finance management then you can join as Assistant Professor or researcher. Later you can progress by virtue of your hard work.
In addition to finance management degree, you can go for post graduate course in Human Resource management. This will give you an added advantage that you will have say in two departments, finance as well as human resources management. The chances of growth in both these fields are more and if any one work hard can progress like anything.
Now you should look for colleges or Universities of your choice, where you can seek admission. At this point my another suggestion would be that you should also look for scholarships offered by concerned colleges and Universities, this will help you to pursue your degree program comfortably and morally. Try to also look for scholarships from Canada Government. If you know some one there, try to contact and explore the things.
Finally, after getting the degree in Finance management and HRM, you will have bright future, therefore listen to your heart and mind.

Good Luck!!!
