The Partnership is not itself currently subject to tax under the Income Tax Act (Canada). Each limited partner of the Partnership generally is required to include in computing the partner's income for a particular taxation year the limited partner's pro rata share of the income of the Partnership for its fiscal year ending in, or coincidentally with, the partner's taxation year end, whether or not any of that income is distributed to the partner in the taxation year. Generally, the amount of income allocated to a limited partner may exceed (or be less than) the amount of cash distributed by the Partnership to such limited partner.
