The taxpayers (a married couple) held a rental property (in dilapidated condition) through a holding company. Boutin JCQ held that they acquired the rental property from the corporation on June 25, 2014, when a notarial deed of sale for the transfer by the corporation to them of the property was executed, rather than on March 6, 2014 when the couple personally agreed (without the corporation as a party) with a contractor to have the existing building demolished and a new personal residence constructed. Since the existing building had been demolished by the later of the two dates, with only the foundation remaining, the property’s supply to the couple was not an exempted supply of a residential complex, and was a taxable supply for QST purposes.
