Executive Summary: Key Legal and Evidentiary Issues

• Central dispute concerns whether $288,162,904 in expenses claimed by Baffinland qualified as Canadian Exploration Expenses (CEEs) under s. 66.1(6)(f) and (g) of the Income Tax Act.

• CRA determined the “existence, location and extent” of the Mary River Mine was established by April 1, 2008, disqualifying subsequent expenses under s. 66.1(6)(f).

• CRA argued that the decision to bring the mine into commercial production was made no earlier than December 19, 2012, rendering earlier expenses ineligible under s. 66.1(6)(g).

• CRA alleged insufficient documentation was provided to support the CEEs, citing lack of specific, quantitative information.

• Baffinland opposed amendments to CRA’s Reply, claiming prejudice due to lost records and employee departures.

• Court allowed CRA’s amendments under Rule 54 and s. 152(9), finding they clarified existing positions without causing injustice.

Background and project details

Baffinland Iron Mines Corporation is a Canadian mining company operating nine high-grade iron ore projects, including the Mary River Mine on Baffin Island in Nunavut. The company claimed Canadian Exploration Expenses (CEEs) and Investment Tax Credits (ITCs) for the 2008 to 2012 taxation years, asserting these expenses were related to bringing the Mary River Mine into commercial production. Specifically, it claimed CEEs totaling $288,162,904 under subsection 66.1(6) and ITCs under subsection 127(9) of the Income Tax Act.

Tax reassessment and positions

The Minister of National Revenue reassessed and issued loss determinations disallowing the CEEs but permitted the amount as current business expenses. The CRA’s position relied on the Purpose Test in paragraphs 66.1(6)(f) and (g):

• Under paragraph 66.1(6)(f), expenses must be incurred "for the purpose of determining the existence, location, extent or quality of a mineral resource in Canada". CRA held that this determination was completed by April 1, 2008, predating the claimed years.

• Under paragraph 66.1(6)(g), expenses must be incurred "for the purpose of bringing a new mine... into production in reasonable commercial quantities" before production began. CRA concluded the decision to bring the mine into production was made on December 19, 2012, after most expenses were incurred.

Baffinland disagreed, asserting that the provisions should be interpreted and applied on an ongoing basis, arguing that CRA’s interpretation created an unintended gap where expenses could not qualify.

Procedural history

• The CRA began an Original Audit of the 2012–2013 tax years in 2015, then extended the audit in October 2017 to include 2010–2011, and in February 2019 to 2008–2009.

• A Notice of Reassessment was issued on September 6, 2019, and Loss Determinations followed on January 7, 2021, for the 2008–2013 years.

• A Notice of Confirmation was issued on November 18, 2021.

• Baffinland filed its Notice of Appeal on February 15, 2022, and CRA filed its Reply on July 20, 2022.

• CRA’s Motion to Amend the Reply was heard on February 29, 2024.

Amendments and evidentiary dispute

CRA sought to amend its Reply to clarify that, in any event, none of the expenses were incurred for the purposes outlined in paragraphs 66.1(6)(f) or (g). The proposed amendments added explicit statements that Baffinland had not incurred the expenses for qualifying purposes and had not provided sufficient documentation to support its claims.

Baffinland opposed the motion, arguing the amendments introduced a new argument not part of the original assessment and would prejudice its ability to respond due to lost records (caused by a 2013 office move, discontinued software, and unavailable staff). They argued the motion failed to meet the requirements of s. 152(9) of the Income Tax Act.

The court’s ruling

Justice Guy R. Smith found that:

• The proposed amendments clarified the CRA’s Reply and were not a new or additional basis.

• Even if they were new, they were permissible under subsection 152(9), as they did not change the legal foundation (still relying on paragraphs 66.1(6)(f) and (g)) and would not increase Baffinland’s tax liability.

• The evidence, particularly from CRA auditor Isabelle Pouliot, confirmed that repeated requests for documentation were made between 2017 and 2019 and were not sufficiently answered.

• The Appellant misunderstood CRA’s position, believing quantum was not in dispute because the CRA accepted the amount as current expenses.

• The lack of documentation was highlighted in both the Objection Report and Notice of Confirmation, which noted the inability to reconcile the claimed expenses to specific qualifying activities.

The Court ruled that allowing the amendments would serve the interests of justice, promote clarity, and would not result in non-compensable injustice.

Final orders

• CRA’s Motion to Amend the Reply was granted.

• Baffinland was permitted to file an Answer within 10 days of service.

• The existing timetable was set aside, with a new one to be jointly proposed within 60 days.

• Costs were fixed at $3,500 payable by Baffinland to the CRA.

This decision, 2025 TCC 73, emphasizes the court's discretionary power to permit amendments that clarify existing legal positions, even if they highlight evidentiary shortcomings acknowledged during earlier administrative stages.
