Jamaican students, or any non-US student, can apply for an International Student Loan to study in Canada through InternationalStudentLoan.com.
There are 2 main requirements. First, your school has to be on the approved list - here's the list of approved Canadian schools: http://www.internationalstudentloan.com ... chools.php
Second, you must have a credit-worthy co-signer that is a US citizen or permanent resident, that has lived in the US for the past two year.
Good luck, hope this helps . . .
