You going for the 1+1 route? It's usually older, mature students who go for that route to save time. For an 18-19 year old who just graduated 12th I would recommend a bachelors (if the family could afford it) or a 2 year diploma. Not because a 1 year program will reduce chances of visa but employers in Canada won't hire you with just 12th + 1 year program on your resume.
Think more long term. If you want to go into healthcare there are so many courses that are better than what you picked, after 12th.
