For the purposes of sections 54.1.1, 54.1.2 and 54.1.5, where a supplier agrees, at any time, to renew, vary, terminate, otherwise than upon the exercise of an option to purchase, or assign a particular agreement for the supply of property by way of lease that is an original leaseback agreement or a subsequent lease in respect of that agreement and the renewal, variation, termination or assignment does not constitute a novation of the particular agreement but has the effect of changing the number of payments that the lessee is obligated to make for supplies by way of lease of the property under the particular agreement, the following rules apply:(1) the supplier and lessee are deemed to have, at that time, entered into a subsequent lease in respect of the original leaseback agreement; and
(2) all supplies by way of lease for which consideration becomes due, or is paid without having become due, at or after the time the renewal, variation, termination or assignment takes effect that would, but for this section, be made under the particular agreement are deemed to be made under that subsequent lease and not under the particular agreement.
