Good option, it is based on total industrial applications, designing of pipes, etc. According to me, you should opt for chemical engineering. After completing you chemical engineering you can work as a process engineer, piping engineer, technical engineer, production engineer, etc.

It depends on the profile that you wish to work in, i.e marketing, operations, finance, HR, etc. If your aim is to join a car company directly from a B-School, then you can specialize in operations, marketing or HR as these are the roles that such companies usually offer to B-School graduates.

I think mechatronics is the most demanding. Do not follow my suggestion blindly, you should wait for another answer.

Your ability and willingness help you to get success in life. Canada is one of the best place for electrical engineers and Canada also need many skillful workers for their growing economy, so don't worry, if you have completed your study in Canada, you can earn Rs.2.5 lakhs to Rs.4 lakhs in a month.
All the best.

As per the last year economic data of Canada government, they need people in civil engineering sector, chemical engineering sector, Oil and gas sector, petroleum sector, renewable energy sector and environmental sector mainly. But, engineers in various sectors are also welcome and also have good prospect.

Both the branches have great prospects in Karnataka, and in India too.
