41.1. Where a person (in this section referred to as the “mandator”) makes a supply, other than an exempt or zero-rated supply, of corporeal movable property to a recipient, otherwise than by auction, in the case where the mandator is not required to collect tax in respect of the supply except as provided in this section and a registrant (in this section referred to as the “mandatary”), in the course of a commercial activity of the mandatary, acts as mandatary in making the supply on behalf of the mandator, the following rules apply:(1) where the mandator is a registrant and the property was last used, or acquired for consumption or use, by the mandator in an endeavour of the mandator, within the meaning of section 42.0.1, and the mandator and the mandatary jointly elect in writing, the supply of the property to the recipient is deemed to be a taxable supply for the following purposes:(a) all purposes of this Title, other than determining whether the mandator may claim an input tax refund in respect of property or services acquired or brought into Québec by the mandator for consumption or use in making the supply to the recipient, and
(b) the purpose of determining whether the mandator may claim an input tax refund in respect of a service supplied by the mandatary relating to the supply of the property to the recipient; and
(2) in any other case, the supply of the property to the recipient is deemed to be a taxable supply made by the mandatary and not by the mandator, and the mandatary is deemed, except for the purposes of section 327.7, not to have made a supply to the mandator of a service relating to the supply of the property to the recipient.
