Missing the RRSP deadline is frustrating, but it’s not a disaster — your unused contribution room carries forward indefinitely, and you can use it next year for an even larger deduction. What you’ve actually lost is one year of tax-sheltered growth, which on a $10,000 contribution at 7% returns amounts to about $700. The best move now: contribute immediately so the money starts growing, and set up automatic monthly contributions to avoid the last-minute scramble next year. If you have a large accumulated room, an RRSP loan can make mathematical sense — a $20,000 contribution at a 35% marginal rate saves $7,000 in tax against roughly $550 in loan interest.

The Bottom Line
Your RRSP room doesn’t expire — contribute now for next year’s deduction and set up automatic contributions so you never miss a deadline again. If you have large accumulated room ($20,000+), consider an RRSP loan: the tax savings almost always exceed the interest cost if you repay within 12 months. In the meantime, maximize your TFSA, check for missed deductions like medical expenses and home office claims, and if you’re a prospective first-time buyer, open an FHSA for a similar tax deduction.
