Is it better to do a one-year diploma course in Canada before applying for MS to improve my chances and publish research papers for a Master's?

Applying directly to a Master's (MS) program in Canada is a better choice for your profile than doing a one-year diploma first.

With your background in Electrical and Electronic Engineering, solid academic record, and extensive work experience, a diploma is unlikely to improve your MS admission chances or help you publish research papers. Diplomas in Canada are mainly for skill development or career shifts, not research or academic advancement.

Focus on strengthening your Master's application through relevant research projects and, if possible, publishing papers based on your academic or professional work. If you need tailored guidance, connect with your LeapScholar counsellor.
