The Adjusted Cost Base (ACB) is the cost of property + any expenses to acquire it, such as commissions and legal fees. The ACB can also include capital expenditures to the property, like the Cost of additions and improvements to the property. Note: You cannot add current expenses like maintenance or repairs to the ACB.
Special rules can apply that will allow you to consider the cost of the property to be an amount other than its actual cost. These rules apply to the following property:
* Identical Properties (Like units of a fund or shares in a corporation)
* Property for which you filed Form T664
* Property you inherit or receive as a gift
