Bank of Nova Scotia v. Canada, 2024 FCA 192, leave granted 22 May 2025 (41643) -- summary under Certainty

In rejecting a submission of the taxpayer that s. 161(7)(b)(iv) was inapplicable to the computation of interest in the situation where its request to carryback a loss to an earlier year was in response to a proposed audit adjustment for the earlier year rather than the situation of a carryback request not being prompted by an unforeseeable adjustment, Woods JA found that, given that “Parliament seeks certainty, predictability and fairness in tax legislation … [i]f Parliament did not intend to impose interest when a loss carryback is claimed as a result of an audit adjustment, it is likely that Parliament would have provided for this with explicit language” (para. 39).
