What is RRSP season? And why is every bank, financial institution, robo-advisor and discount brokerage telling you "Quick, the deadline is looming! Don't forget to contribute to your RRSP before it's too late!" That's because March 2, 2020 is the deadline for you to contribute to your RRSP to count towards the 2019 tax year (typically it's March 1, but this year March 1 is on a Sunday). So if you are trying to figure out to reduce your taxes owing for 2019, you may want to take this opportunity to contribute to your RRSP now before the deadline to use as a tax deduction when filing your 2019 taxes.
