We are planning to put $2500 a year (208.33/month) into this plan. Am little biased since I sell the product. Main advantage is education bonus of up to 15% of the contributions to the RESP will increase the income paid as Educational Assistance Payments (EAPs) to go along with any the fund and any growth plus the grants.
