Should I report a portion of the CCA recapture based on the average business use percentage over the life of the vehicle when there was no business mileage in 2017? T2125

Background: I sold my vehicle in 2017 that I have used both professionally (sole proprietor) and personally in the past and did not purchase a replacement vehicle.  This resulted in a recapture of CCA in the amount of $X,000 in 2017.  I have no business income or expenses to report in 2017 as I elected to discontinue the business in 2017.  Given I have no business mileage, there's no percentage being applied to the CCA recapture and subsequently no income to add or tax liability being calculated.
