As a general rule, you can contribute to your (RRSP) as long as you have earned income from employment or self-employment and you have contribution room. You are also allowed to contribute to your RRSP in the year you become a resident of Canada, even if you have not yet received any Canadian income.
The contribution limit for RRSPs is generally based on your earned income from the previous year, and any unused contribution room carries forward to future years. This means that if you did not have any earned income in 2021, you likely did not have any contribution room for that year. However, if you started working in March 2022 and earned income during that year, you would be able to contribute to your RRSP in 2022 based on your earned income for that year.
It's worth noting that there are certain situations in which new immigrants to Canada may have contribution room even if they have not yet received any Canadian income. For example, if you were a resident of Canada for part of the year and received income from a foreign source, you may be able to contribute to your RRSP based on that income. Additionally, if you have a spouse or common-law partner who has contributed to their own RRSP, you may be able to contribute to your own RRSP using the "spousal RRSP" rules.
In summary, if you started working in March 2022 and made contributions to your RRSP in November of that year based on your earned income for 2022, your contributions are likely to be valid. However, it's always a good idea to check with the Canada Revenue Agency or a tax professional to confirm your specific situation and make sure you are making contributions within the limits that apply to you.
