Six months after a student ceases being enrolled full-time in an educational institution, a loan contracted with the Canada student loans program is said to be consolidated and its repayment is expected. Many ex-students will repay their loan in total (capital and interest) within a ten-year period. However, a non-negligible proportion of borrowers will experience difficulty in the repayment of their loans. We are able to shed a new light on these issues because we have access to unique data to estimate econometric models of the determinants of interest relief and claims (defaults) as well as duration models for the repayment of student loans. We found that finishing the program supported by a loan is essential to avoiding default. Therefore, it may be worth considering policies that will reward anyone who completes his or her program. On the other hand, too much flexibility in access to loans might encourage experiments by students that could turn disastrous for the student and the national loan program. A loan program should also come with some information on the risk involved for the student before he or she invests in a particular field or program. One particular concern is the relatively high level of default for students attending private schools. Relatively easy access to loans could be an invitation for private institutions to capitalize on that fact with various educational programs having little bearing on the reality of the labour market. Eventually serious institutions will establish a reputation, but for some students it will be too late. Another result concerns the interest relief measure that seems not to have played its role of helping the 1990-91 cohort of students to pass through difficult times.
