GST/HSTC notice

Hi All,

As we landed last year form US to Canada on Oct, we submitted our returns this year first time for 2021.
Yesterday, I received a notice from IRCC called “GST/HSTC notice”.

This notice states that they don’t have my world wide income, so cannot calculate our GST/HSTC.

Kindly help me to understand what is this GST/HST credit and confirm if there is any action required from my end.

Appreciate all your help till now.

I got the same and is in similar situation.

“Ignore” per my tax consultant. if income is more than threshold then it can be ignored.
