4. (1) The following rules apply to the calculation of the amount of rural or remote rate reduction for rural residential consumers served by subsidiaries of the Services Corporation: 1. The Board shall calculate the weighted average municipal bill in the following manner: i. For each municipal distributor, multiply the number of municipal residential consumers to whom the municipal distributor distributes electricity by the amount payable to the municipal distributor by a municipal residential consumer for the first 1,000 kilowatt hours of electricity consumed per month, not including any amount payable under subsection 79 (4) of the Act towards compensation for lost revenue resulting from rural or remote rate reduction. ii. Add together the products determined under subparagraph i in respect of all municipal distributors. iii. Divide the sum determined under subparagraph ii by the total number of municipal residential consumers to whom electricity is distributed by municipal distributors. 2. The Board shall calculate the weighted average rural bill for subsidiaries of the Services Corporation in the following manner: i. For each rate class that applies to rural residential consumers served by subsidiaries of the Services Corporation, multiply the number of premises occupied by those consumers to which the rate class applies by the amount that would be payable for the first 1,000 kilowatt hours of electricity consumed per month in those premises, not including any amount payable under subsection 79 (4) of the Act towards compensation for lost revenue resulting from rural or remote rate reduction. ii. Add together the products determined under subparagraph i in respect of all rate classes that apply to rural residential consumers served by subsidiaries of the Services Corporation. iii. Divide the sum determined under subparagraph ii by the total number of premises occupied by rural residential consumers served by subsidiaries of the Services Corporation. 3. The Board shall calculate the amount of rural or remote rate reduction for rural residential consumers served by subsidiaries of the Services Corporation in a manner that the Board forecasts will result in the weighted average rural bill for subsidiaries of the Services Corporation calculated under paragraph 2 not exceeding the weighted average municipal bill by more than 15 per cent. 4. Paragraph 3 does not prohibit the Board from calculating the amount of rural or remote rate reduction in a manner that results in the amount payable by particular consumers exceeding the weighted average municipal bill by more than 15 per cent.  O. Reg. 315/99, s. 4 (1). (2) The Board shall calculate the amount of rural or remote rate reduction for remote community consumers in a manner that ensures that the rates charged to those consumers are no greater than the rates charged to the lowest-density comparable class of consumers in other areas of Ontario in which electricity is distributed by subsidiaries of the Services Corporation. O. Reg. 315/99, s. 4 (2). (3) Subject to subsection (4), the Board shall calculate the amount of rural or remote rate reduction for consumers referred to in paragraph 3 of subsection 3 (1) who occupy premises that are located in a municipality referred to in the Schedules in a manner that ensures that the total amount of rural or remote rate reduction for those consumers in each period set out in the Schedule that is applicable to that municipality is equal to the amount set out for that period in that Schedule.

(4) The Board shall calculate the amount of rural or remote rate reduction for consumers referred to in paragraph 3 of subsection 3 (1) who occupy premises that are located in a municipality referred to in the Schedules in a manner that ensures that the total amount of rural or remote rate reduction for those consumers for the period during which paragraph 3 of subsection 3 (1) applies to those consumers is equal to the sum of the amounts set out for all the periods set out in the Schedule that is applicable to that municipality, reduced by the amount paid under subsection 83.7 (24) of the Power Corporation Act in respect of employees who, under section 83.7 of that Act, accept employment with the distributor that distributes electricity to those consumers. O. Reg. 315/99, s. 4 (4).

For Attawapiskat, the amount of $640,000. 2. For Fort Albany, the amount of $360,000. 3. For Kashechewan, the amount of $600,000. O. Reg. 2/01, s. 3.
