CRA confirms that exempting a capital gain doubles the CDA addition

The capital dividend account definition provides for the addition of the difference between the corporation’s capital gain from a disposition and the portion of that capital gain which is a taxable capital gain. Therefore, if the taxable capital gain resulting from the disposition is nil (for example, for a donation of ecologically sensitive lands exempted under s. 38(a.2)(i)), the full amount of the capital gain will be added to the CDA.
