Please note that the climate action incentive is given automatically and if they are married- it will be given to the one whom the CRA will receive their return first. This will not affect the amount owing or refund amount. As per the CRA:
The Government of Canada has changed the climate action incentive from a refundable credit claimed annually on personal income tax and benefit returns to quarterly tax-free payments made through the CRA benefit system starting in July 2022.
