A line of credit is a type of loan that lets you borrow money repeatedly up to a pre-set limit. You can borrow money from a line of credit, pay it back and then borrow again, up to your credit limit.
A student line of credit is a product for students that helps them pay for expenses related to post-secondary education, like tuition or books. You can apply for a student line of credit at any time. Usually, you apply online, over the phone or in person. You usually need to provide proof that you're either a full-time or part-time student at a recognized Canadian post-secondary institution to be eligible for a student line of credit.
