Class 8 with a CCA rate of 20% includes certain property that is not included in another class. Examples are furniture, appliances, and tools costing $500 or more per tool, some fixtures, machinery, outdoor advertising signs, refrigeration equipment, and other equipment you use in the business.
Note: If this equipment costs $1,000 or more, you can elect to have it included in a separate class. The CCA rate will not change but a separate CCA deduction can now be calculated for a five-year period. When all the property in the class is disposed of, the undepreciated capital cost (UCC) is fully deductible as a terminal loss. Any UCC balance remaining in the separate class at the end of the fifth year has to be transferred back to the general class in which it would otherwise belong. To make an election, attach a letter to your income tax return for the tax year in which you acquired the property.
