I think you will have to write a very strong statement of purpose (SOP). If I'm not mistaken, you have already been rejected twice. One of the problems you are going to face is that University Canada West is not a very good university. Because this school has a bad reputation in Canada, you will not be able to say things like "this is one of the best schools in Canada" in your SOP. And it may be hard to convince CIC that University Canada West can provide a higher quality of education than the schools in Ghana. So you will have to find other reasons why you want to attend this school. I suppose you could say that you want a Western business education. Other than that, I'm not sure what to suggest.
Good luck...
