Grant room can be carried forward but there are still situations where the December 31st contribution date should be considered. If there are less than seven years before your child or grandchild turns 17 and you haven’t maximized RESP contributions, consider making a contribution by December 31st. If a child or grandchild turned 15 during the year and has never been a beneficiary of an RESP, December 31st is the last chance to contribute a minimum of $2,000 to an RESP in order to collect the 20% (Canada Education Savings Grant) for the current year and be eligible to the CESG for the following years.
