hello samiksha, 

once you are done with the BDS course from India, dont just rush all at once rush your application and only do that once you are fully aware of the licensure procedure and the regulatory body’s expectations from you.

first of all, as canada is a very favourable place for dentists, know your worth and check for visa applications.
