Question about GST/HSTC request I received

[AS2024]

So I filed my taxes for the 1st time in Canada this year (for 2023). And got the tax returns deposited into my bank account in April. I just received the following email from CRA:

The CRA cannot calculate the amount of the CCR you may be entitled to receive for April 2024 to January 2025 without the following information:
- your world income, converted to Canadian dollars, for the period in 2023 before you came to Canada
- your spouse's or common-law partner's world income, converted to Canadian dollars, for the period in 2023 before they came to Canada

I had no income before coming to Canada in 2023 (I moved in May). So what do I submit here? Do I call saying I earned no income before moving to Canada? Do I have to mail them with some documents?

Any help is greatly appreciated.

Thank you.

Thanks, but this doesn't really help. It's obvious that I can call the CRA for assistance 🙂
