Annual basic amortization contributions after June 30, 2011
 7. (1) The employer (or a person or entity required to make contributions on behalf of the employer) shall make the annual contribution that is required by this section (the “annual basic amortization contribution”) to each of the participating Ontario pension plans for each 12-month period that begins on July 1, 2011 or on July 1 of a subsequent year.  O. Reg. 196/11, s. 7 (1). (1.1) This section does not apply with respect to a 12-month period that begins on or after July 1, 2017 if the employer has filed an election in accordance with section 8 to have that section apply. O. Reg. 464/16, s. 2. (2) The amount of the annual basic amortization contribution for the 12-month period that begins on July 1 of a particular year is determined using the information in the annual combined report prepared with reference to the valuation date that falls on December 31 of the previous year.  O. Reg. 196/11, s. 7 (2). (3) The annual basic amortization contribution is payable in equal monthly instalments, and the amount payable for each month is due on or before the last business day of the month.  O. Reg. 196/11, s. 7 (3). (4) The amount of the annual basic amortization contribution that must be made to a particular participating Ontario pension plan under this section for a particular month during the 12-month period is calculated using the formula, A × B/C in which, “A” is $4,166,667 for any month before July 2014 and is $6,666,667 for any month after June 2014, “B” is the amount of the adjusted solvency deficiency of the plan as of the applicable valuation date, and “C” is the sum of the adjusted solvency deficiencies for every participating pension plan as of the applicable valuation date. O. Reg. 105/14, s. 5. (5) The obligation to make the annual basic amortization contribution to a particular Ontario pension plan is terminated when the pension plan ceases to be a participating pension plan.  O. Reg. 196/11, s. 7 (5). (6) If an Ontario or Quebec pension plan ceases to be a participating pension plan before its annual basic amortization contribution is made in whole or in part under this section (or under the corresponding provision of the Quebec Regulation) to that pension plan, the amount of the unpaid annual basic amortization contribution to be made to that pension plan shall be reallocated among the remaining participating pension plans in accordance with the formula set out in subsection (4).  O. Reg. 196/11, s. 7 (6). (6.1) Despite subsection (6), the following rule applies if an election is filed in accordance with section 8 to have that section apply: 1. If a Quebec pension plan ceases to be a participating pension plan on or before December 31, 2016, the amount of the unpaid annual basic amortization contribution to be made for a month after December 2016 and before July 2017 to that pension plan shall not be reallocated among the remaining participating pension plans. O. Reg. 464/16, s. 2. (7) The portion of the annual basic amortization contribution for a particular month reallocated to a particular participating Ontario pension plan is payable to the pension plan as a lump sum within 30 days after the end of the 12-month period described in subsection (1) as it would have been payable to the formerly-participating pension plan.  O. Reg. 196/11, s. 7 (7). (8) Despite subsections (5), (6) and (7), if a particular Ontario pension plan ceases to be a participating pension plan because it is fully funded before December 31, 2020, (a) the obligation to make the annual basic amortization contribution to the pension plan ends on June 30 after the valuation date of the final report filed under section 32; and (b) the monthly contributions made from that valuation date to that June 30th are deemed to be special payments under clause 5 (1) (e) of the General Regulation for purposes of the calculation of present value referred to in clause 1.2 (1) (d) of the General Regulation.  O. Reg. 196/11, s. 7 (8).
