693.3. Section 693.2 does not apply in respect of a taxpayer, in relation to a given partnership, if the Minister is of the opinion that the interposition, between the taxpayer and the given partnership, of one or more other partnerships is part of an operation or transaction or of a series of operations or transactions, one of the purposes of which is to cause the taxpayer to be able to deduct, in computing the taxpayer’s taxable income for a taxation year under a provision of this Book, an amount greater than the amount that the taxpayer could have so deducted for that taxation year, but for that interposition.
