21 (1) For the purpose of clause 19(1)(a)(i)(A), the simulated yield of the average provincial and territorial personal income tax for the territory for a taxation year ending in a fiscal year shall be determined by means of the micro-simulation model by,

• (a) simulating, in turn, the amounts, aggregated over all individuals in the territory, of provincial and territorial personal income tax that would be derived by the territory from those individuals in the taxation year under each of the personal income tax systems of the 10 provinces and the three territories as if those personal income tax systems applied to the individuals in the territory;

• (b) calculating a weight for the personal income tax system of each of the 10 provinces and the three territories equal to a fraction

  • (i) whose numerator is the revenue for the fiscal year, as set out in the certificate, from the taxes imposed by a province or territory on the income of individuals, as described in subparagraph 18(a)(i), that is derived by the territory with the personal income tax system for which the weight is being calculated, and

  • (ii) whose denominator is the aggregate, over the 10 provinces and the three territories, of the revenue referred to in subparagraph (i);

• (c) multiplying each amount simulated under paragraph (a) by the respective weight calculated under paragraph (b); and

• (d) calculating the aggregate of the 13 products calculated under paragraph (c).
