Duty to calculate
 12. (1) This section applies to a person who engages in electricity importation, natural gas distribution or petroleum product supply, as described in paragraphs 1, 2 and 3 of subsection 9 (3) of the Act. (2) If the person satisfies the criteria set out opposite the person in Column 2 of the Table to this section, the person is required to calculate the amount of the greenhouse gas emissions associated with a prescribed activity. (3) The prescribed activity of the person, in respect of which greenhouse gas emissions must be calculated, is the activity set out opposite the person in Column 3 of the Table to this section. (4) The amount of the greenhouse gas emissions associated with the prescribed activity to be calculated is the amount set out opposite the person in Column 4 of the Table to this section. (5) The period in respect of which the calculations must be made is a year. (6) The person shall, subject to subsection (7), use the standard quantification method or methods set out in the Guideline to calculate the amount of greenhouse gas emissions associated with the prescribed activity. O. Reg. 143/16, s. 12 (6); O. Reg. 449/17, s. 6. (7) With respect to calculations of greenhouse gas emissions associated with natural gas distribution, the person may use a method other than the standard quantification methods in quantifying a maximum of the lesser of 20,000 tonnes and 3 per cent of the greenhouse gas emissions associated with the activity. (8) The following rules apply where the standard quantification methods in respect of an activity include a choice of calculation methodologies: 1. The person shall select one of the calculation methodologies and use it for all subsequent quantifications in respect of the activity, unless the Director consents in writing to the use of another methodology. 2. If the Director consents to the use of another methodology, the person shall use the methodology consented to for all subsequent quantifications in respect of the activity, unless the Director consents in writing to the use of another methodology. (9) All amounts of greenhouse gas emissions calculated shall be expressed as tonnes of CO2e. (10) If the amount of greenhouse gas emissions associated with a prescribed activity is a number that is not a whole number when expressed in tonnes, the number shall be rounded up to the nearest tonne. (11) The prescribed activity in Column 3 of Item 3 of the Table to this section includes the supply of a petroleum product only if the supply meets the following criteria: 1. The product must be supplied for use as a fuel in an application other than aviation or marine applications. 2. If the product is supplied by first placing it on the Ontario market through its use in Ontario, the use must not be at a petroleum refinery or at a fractionation facility. 3.  Revoked: O. Reg. 474/16, s. 10 (1). O. Reg. 143/16, s. 12 (11); O. Reg. 474/16, s. 10 (1). (12) For the purposes of this Regulation, a transfer or sale of a petroleum product to the owner or operator of a petroleum refinery or fractionation facility in Canada is not first placing the petroleum product on the Ontario market. O. Reg. 474/16, s. 10 (2). (13) If there is a change during a year in the owner or operator of a pipeline transportation system used for natural gas distribution, the owner or operator at the end of the year is deemed to have been the owner or operator for the entire year.

  2.   A person who distributes natural gas in Ontario.   The person must physically deliver natural gas to a person in Ontario for consumption by the person to whom it was delivered.   Physically delivering natural gas to a person in Ontario for consumption by the person to whom it was delivered.   The amount of greenhouse gas that would be emitted from the consumption of the natural gas distributed by the person. 

  3.   A person who supplies petroleum products for consumption in Ontario.   The person must be one of the following: 1.  An owner or operator of a petroleum refinery. 2.  An owner or operator of a fractionation facility. 3.  A person who imports a petroleum product into Ontario.

The amount of greenhouse gas that would be emitted from the use of the petroleum products supplied by the person. O. Reg. 143/16, s. 12, Table; O. Reg. 474/16, s. 10 (3); O. Reg. 258/17, s. 6.
