 10. (1) The amount of the subsidy for a service referred to in subsection 8 (1) for which a parent is eligible on the basis of their adjusted income is calculated as follows: 1.  Determine the amount the parent would pay for the service if the parent did not receive any subsidy. 2.  Determine the amount the parent shall pay as calculated under subsections (2) to (5). 3.  Subtract the number determined under paragraph 2 from the number determined under paragraph 1. O. Reg. 138/15, s. 10 (1); O. Reg. 237/22, s. 1 (1). (2) A parent shall not pay any of the cost of the service for their children if the parent, (a)  has a total adjusted income of $20,000 or less; or (b)  the amount the parent would contribute on the basis of their adjusted income for each month of child care, as calculated under subsection (3), is less than $10. O. Reg. 138/15, s. 10 (2). (3) If a parent has a total adjusted income of more than $20,000 and the child is in receipt of the service on a full-time basis, the service system manager shall calculate a monthly amount that the parent shall pay, as follows: [(A × 0.10) + (B × 0.30)] ÷ 12 where, A  is the amount by which their adjusted income exceeds $20,000 but is not more than $40,000, and B  is the amount by which their adjusted income exceeds $40,000. O. Reg. 138/15, s. 10 (3). (4) If a parent has a total adjusted income of more than $20,000 and the child is in receipt of the service on a part-time basis, the service system manager shall calculate a daily amount that the parent shall pay as follows: A ÷ (B × 4.35) where, A  is the monthly amount paid by the parent for the service determined under subsection (3), and B  is the number of days per week the child is in receipt of the service. O. Reg. 138/15, s. 10 (4). (5) If a parent has at least one eligible child, as defined in Ontario Regulation 137/15 (General) made under the Act, who is enrolled in a child care centre or home child care that is part of the Canada-Wide Early Learning and Child Care System, the service system manager shall reduce the amount calculated under subsection (3) or (4) that the parent shall pay by the following amount: A ÷ B × C × D where, A  is the amount determined under subsection (3) or (4), as the case may be, B  is the number of children in respect of whom the parent must pay an amount in accordance with subsection (3) or (4), as the case may be, C  is the number of children in respect of whom the parent must pay an amount in accordance with subsection (3) or (4), as the case may be, who are eligible children enrolled in a child care centre or home child care that is part of the Canada-Wide Early Learning and Child Care System, and D  is 0.25, if the amount determined under subsection (3) or (4) is in respect of services rendered before December 31, 2022, and is 0.5, if the amount determined under subsection (3) or (4) is in respect of services rendered on or after December 31, 2022. O. Reg. 237/22, s. 1 (2); O. Reg. 543/22, s. 1 (1, 2).
