In this first instance, provinces were given until September 2018 to indicate their plans. We have indicated where the federal system will apply going forward.
In a letter from Minister McKenna and Minister Morneau to their provincial and territorial counterparts in December 2017, in order to provide certainty—for example, for business decisions and investors and consumers—they indicated that where the federal system applied, it would stay in effect until 2022. That coincides with the timing of the commitment to do a federal-provincial-territorial review of the system to help inform the path forward.
Conversely, as you noted, there may be changes over time in terms of different systems. For example, the assessment process to ensure that all proposed or existing systems align with the common criteria, which we refer to as a benchmark, is done on an ongoing basis. The systems will be assessed annually to ensure they continue to align with those common criteria.
That will be ongoing monitoring in terms of changes over time, but where the federal system applies, the intent is that it stays in effect until 2022.
