274.4. Where a person not resident in Canada disposes of a taxable Québec property that the person last acquired before 27 April 1995, that would not be a taxable Québec property immediately before the disposition if sections 1087 to 1096.2 were read as they applied in respect of dispositions that occurred on 26 April 1995 and that would be a taxable Québec property immediately before the disposition if those sections were read as they applied in respect of dispositions that occurred on 1 January 1996, the person’s gain or loss from the disposition is deemed to be the amount determined by the formula
