You are required to meet LICO each year until the application is approved. So you are not technically safe if you don't meet income requirements for 2022. Having said that, there is no guarantee IRCC will even check this. They may or may not. So you could end up being fine or it may be an issue.
I had even received the below letter long long time ago and it says 3 years BEFORE receiving the application:
"
Dear _____
This letter confirms that your Application to Sponsor a Member of the Family Class was received
by Immigration, Refugees and Citizenship Canada (IRCC) at the Case Processing Centre in
Mississauga on behalf of the following family member(s):
___
Please note that the following documentation will be required for your sponsorship
application to determine whether you meet the minimum necessary income requirements to
sponsor a parent or grandparent. In order to minimize processing delays, if not already included
in your application, please obtain and submit as soon as possible:
A completed and signed authorization form – IMM 5768 - Financial Evaluation for Parents
and Grandparents Sponsorship providing your Social Insurance Number.
o If you selected “Yes” to the Statement of Consent on this form and provided your
Social Insurance Number, you authorize IRCC to request information from Canada
Revenue Agency (CRA) in regards to your, or the cosigner’s (if applicable), income
tax information for the
three consecutive years immediately preceding the received
date of your application."
