Mr. Chair, the amendment, as Mr. Fergus indicated, is a clarification of the government's policy intent. It has been articulated in a series of documents that are public, starting with the pan-Canadian approach to pricing carbon pollution. That's the document that sets out the basic test or criteria the federal government will use to determine or assess the provincial and territorial pricing systems.
As the amendment suggests, the core of that test is stringency. Recognizing that there are different kinds of pricing systems, some that have an explicit price and some that work by means of imposing a cap or performance standard that in turn translates into a market price, the document describes the way in which stringency will be assessed for both types of systems.
That test was then elaborated in a guidance document that was published in mid-2017, in a supplemental guidance published later in 2017, then in a letter from ministers Morneau and McKenna to their provincial counterparts sent in December 2017, and also on the web. Most recently, it was outlined in a letter from our deputy minister of environment and climate change to his counterparts on May 4, also available publicly.
Those documents provide clarification about the way in which the government will interpret this concept of stringency. It relates to the explicit price or the nature of the cap or standard that's set by the pricing system, depending on the nature of the system that's in place.
