My mother's sister, her husband and my mother's parents are all in Canada. How do I get to Canada?

How many relatives are in Canada is not a reason for immigration. This is only a slight advantage. You can get a little extra points when scoring skilled immigrants. The key is one's education and other factors.

I wonder how old you are. If you are still a student, you can apply for studying abroad. It is an advantage if your relatives over there are willing to help you. If you have already worked, I suggest you evaluate your score.
