We just did some preliminary tax calculations and thanks to carried-over tuition/education amounts from previous years, and our RRSP contributions from last year, we will be getting a tax refund of around $9500. Sorry you can't "act now to receive my amazing tax secrets." We just had a lot of tuition credits to use, but we have now used up all our tuition/education amounts so that will be the last time we have that kind of a refund. We will either be putting that refund into our RRSPs, then reducing our monthly RRSP contributions over the next 12 months, thereby increasing the amount we can put down our student line of credit each month, OR putting it down on the line of credit thus reducing the amount of interest we have to pay on the loan each month, thereby increasing the amount of principal paid each month. Either way, it doesn't really matter too much. I figure the risk-adjusted return on the RRSP compared to the line of credit is about the same. Although the student line of credit is at prime so the return there is really low.
