Could somebody just confirm whether I got it right? Whatever I contributed to my RRSP between Jan 1 and March 4 of 2025, and was declared in the 2024 tax returns, counted towards 2024. If my Notice of Assessment for 2024 says

Your available RRSP contribution room for 2025: $10,000

then it actually means I can contribute that much from March of 2025 until March of 2026 (whatever I contributed in the beginning of 2025 is a done deal).
