(17)This Decision recognises equivalence of binding requirements set out in Canadian law relating to OTC derivative contracts applicable at the time of adoption of this Decision. The Commission, in cooperation with ESMA, will monitor on a regular basis the evolution of the legal, supervisory and enforcement arrangements for these OTC derivative contracts and their consistent and effective implementation, regarding the timely confirmation, portfolio compression and reconciliation, valuation, dispute resolution and margin requirements applicable to OTC derivative contracts, not cleared by a CCP with respect to which this Decision has been taken. As part of its monitoring efforts the Commission may request OSFI to provide information on regulatory and supervisory developments. The Commission may undertake a specific review at any time, where relevant developments make it necessary for the Commission to reassess the declaration of equivalence granted by this Decision. Such reassessment may lead to the repeal of this Decision, which would as a consequence make counterparties automatically subject again to all requirements laid down in Regulation (EU) No 648/2012.
