In India the minimum requirement to become a pilot is to be a Grade 12th Passout with Physics, Maths and English as your subjects.
So you cannot find any job in India as a fresher therefore it is better to pass out from high school first then do it from Australia and according to Indians, Australia is a good place to learn flying, many Indians go to Australia for CPL.
Canada isn't ideal due to its bad weather, flying months are less plus Aviation degrees aren't very progressive or helpful to make you a pilot, it is better do it from a flying academy or after having a good graduation degree which can get you into an alternate job as a security measure.
All the best.
