As at March 31, 2021, net deferred tax assets of $85.8 million (2020 – $27.8 million) were recognized in jurisdictions that incurred losses this fiscal year or the preceding fiscal year. Based upon the level of historical taxable income or projections for future taxable income, management believes it is probable that the Company will realize the benefits of these net deferred tax assets.

As at March 31, 2021, a deferred income tax liability on taxable temporary differences of $2,439.9 million (2020 – $2,544.3 million) related to investments in subsidiaries and interests in joint ventures has not been recognized, because the Company controls whether the liability will be incurred and it is satisfied that it will not be incurred in the foreseeable future.

The non-capital losses incurred in various jurisdictions expire as follows:


Expiry date	Unrecognized		Recognized






2022 - 2026	$	72.3	$	7.2
2027 - 2040		51.7		68.2
No expiry date		64.7		113.2
	$	188.7	$	188.6

As at March 31, 2021, the Company has $107.4 million (2020 – $149.9 million) of deductible temporary differences for which deferred tax assets have not been recognized. These amounts will reverse during a period of up to 25 years.
