S14 shows the Census metropolitan areas but one has to go elsewhere to find out just which municipalities are included and which aren't.  I googled "CRA climate action incentive 2022" and got the following link:

https://www.canada.ca/en/revenue-agency/services/child-family-benefits/cai-payment.html

I then drilled down to get a map of my local census metropolitan area (Calgary) which gave me a useless map of North America, but did give me a list of municipalities.  It took some digging, but finally did get to the Calgary CMA on the Gov't of Alta website.  One really has to do this as there is neither rhyme nor reason as to which surrounding communities are included and which are not; Cochrane and De Winton are about the same distance from downtown Calgary, but Cochrane is part of the CMA while De Winton is not.  Crossfield is further from the city centre than Okotoks but - you guessed it - Crossfield is in and Okotoks is out.  It looks as if Rocky View County (surrounding the north of half of Calgary) has been included while Foothills County (surrounding the south half of Calgary) has been excluded though both are roughly equidistant to Calgary and both have similar mixes of rural and urban centres.

Hope this helps.
