What is a CMA in relation to the Climate refund and where you live?

A census metropolitan area (CMA) is one or more adjacent municipalities centred on a population centre that has a large number of inhabitants. If you live outside of one of these CMAs, you get a small amount added to your Climate Action Incentive credit. The CRA has more information on the CMAs:

Is my municipality (Town of Canmore) a part of CMA if it is not not listed by CRA but the municipality has blue border in CRA map? Thank you.

If it’s not listed as part of a CMA, and it’s not within the (purple) border of a CMA, then it’s not part of a CMA.

I try to 'tick the box' on line 60102 (and several others), but it will not mark the box.  Have tried typing X, typing x, double clicking, right clicking, left clicking.  Suggestions?
