But today, there’s less fanfare.“There’s not as much buzz around RRSPs,” he said.One reason is the decline in physical bank visits. With the rise of online banking and do-it-yourself investing, fewer people interact with bankers face-to-face, reducing the pressure to make last-minute contributions, Mr. Heath said. Another factor is competition.Before 2009, RRSPs were the “only game in town” for Canadians, with many making a single annual deposit, Mr. Heath said. But the introduction of the tax-free savings account and, more recently, the first home savings account, has shifted how Canadians save. By 2014, the average contribution to TFSAs exceeded those for RRSPs.Anita Bruinsma, certified financial planner and owner of Clarity Personal Finance, said that she has also seen a rise in employers offering group RRSP plans, where people have RRSP contributions automatically withdrawn from their paycheques.Financial planners see advantages to making smaller, regular contributions throughout the year rather than a single, large payment.Spreading out investments offers more time in the market, meaning more compound growth, and it reduces exposure risk, said David Field, a certified financial planner and founder of Papyrus Planning.Regular contributions can make saving more manageable by splitting it up into smaller parts while also lowering the temptation to spend the money elsewhere, Mr. Heath said. Additionally, smaller, consistent contributions help investors avoid missing the RRSP deadline altogether.If you do make regular RRSP contributions, you can reduce the tax deducted by your employer, Mr. Field said. To do this, you can submit form T1213 to the Canada Revenue Agency. If approve
