Methods of apportionment
 7. (1) Subject to subsections 8 to 11, an authority may apportion a reduced operating expense or a reduced capital cost among its participating municipalities in accordance with one of the following methods of apportionment: 1. The MCVA apportionment method described in subsections (2), (3), (4) and (5). 2. The benefit-based apportionment method described in subsection (6). (2) Under the MCVA apportionment method, the portion of a reduced operating expense or of a reduced capital cost to be apportioned to a participating municipality shall be based on the ratio that the participating municipality’s modified current value assessment bears to the authority’s modified current value assessment. (3) For the purposes of subsection (2), a participating municipality’s modified current value assessment shall be determined as follows: 1. For each of the property classes set out in Column 2 of the Table to this subsection, determine the sum of the current value assessment for all the properties in the municipality that are in the property class, if any. 2. Multiply the current value assessment for each property class by the factor set out in Column 3 of the Table to this subsection opposite the property class. 3. Determine the sum of the amounts obtained under paragraph 2. 4. Multiply the sum obtained under paragraph 3 by a percentage based on one of the following ratios: i. If apportioning an operating expense or capital cost that is related to a program or service provided under the Clean Water Act, 2006, the ratio of the amount of the municipality’s land that is in the source protection area for which the authority is the source protection authority under that Act to the total amount of land in the municipality. ii. If apportioning any other operating expense or capital cost, the ratio of the amount of the municipality’s land that is in the jurisdiction of the authority under the Act to the total amount of land in the municipality. table   property classes and factors Column 1   Item   Column 2   Property Class   Column 3   Factor

(5) For the purposes of subsection (2), an authority’s modified current value assessment shall be equal to the sum of the modified current value assessments for, (a) if apportioning an operating expense or a capital cost that is related to a program or service provided under the Clean Water Act, 2006, every participating municipality in the source protection area for which the authority is a source protection authority under that Act; and (b) if apportioning any other operating expense or capital cost, every participating municipality within the authority’s area of jurisdiction. (6) Under the benefit-based apportionment method, the authority shall apportion an operating expense or capital cost by, (a) evaluating the benefit that each participating municipality obtains from the program or service to which the operating expense or capital cost is related; and (b) allocating to each participating municipality a portion of the reduced operating expense or reduced capital cost that is based on the ratio of the benefit afforded to the participating municipality by the program or service referred to in clause (a), relative to the overall benefit afforded by the program or service to all benefitting participating municipalities.
