Medical school admissions

[Ranjit4]

Hello, I just finished my fourth and final year of undergraduate studies. I am applying to both Canadian and Caribbean medical schools, but I am uncertain as to whether I will receive admission in Canada. I had a very poor gpa in my second year which is pulling my entire cgpa down. I was thinking of doing a 5th year to bring up my gpa, but this will not guarantee me a spot in Canada. Another downside is that if I do a 5th year, I will have to wait until 2014 to start medical school in Canada. I believe my credentials are good enough to get accepted to the Caribbean (specifically Saba), but I want admission in Canada. Should I do a 5th year of undergraduate work to pull up my gpa and perhaps have a better chance of staying in Canada, or should I not risk the time delay and just start medical school at Saba?
I know Saba is reputable, but it is still a Caribbean school and residency is not a guarantee.
I would appreciate any insight and assistance.
Thank you.
