Hello student why in Canada why not in your own country India there's lots of future after pursing Bachelor of Dental Science in India as well as in Canada. As Dentist are always in demand and get a well packaged of salary to get work in any client/hospital. They can also start their own seprate clink and run it for sure. There's always lots of patients and demands in Dental issues.

Feel free to comment if you have any doubt

Good luck
