"Generally, you have to pay a tax of 1% per month on your unused contributions that exceed your RRSP deduction limit by more than $2,000" from: [Excess Contributions - Canada.ca](https://www.canada.ca/en/revenue-agency/services/tax/individuals/topics/rrsps-related-plans/contributing-a-rrsp-prpp/what-happens-you-over-your-rrsp-prpp-deduction-limit.html)
I did it on purpose because I wanted to take advantage of the upcoming volatility due to a possibly-very-near Supreme Court ruling on POTUS's tariffs. I do know that POTUS has "back- up plans" that will be very close to the existing (illegal) tariffs. TIA!!
