Tax law 2025 FCA 221

Azmayesh-Fard v. Canada

The Federal Court of Appeal dismissed the appellant’s appeal because the Tax Court’s findings that the reassessments were not statute barred, that the taxpayer’s nondisclosures amounted to at least negligence or wilful blindness, and that gross negligence and T1135 penalties applied were supported by the agreed facts and not tainted by palpable and overriding error; the Crown was not required to call the taxpayer and costs of $3,300 were awarded to the respondent.

  • Reassessment beyond normal reassessment period
  • Gross negligence penalties
  • Failure to disclose foreign property (t1135)
  • Statute-barred reassessments

Occupational health and safety law 2025 ONCA 426

Ontario (Labour, Immigration, Training and Skills Development) v. Benevides

Leave to appeal was granted on three issues because the proper identification of the actus reus for worker offences under the OHSA, the proper approach to concurrent/overlapping responsibilities, and the role of private contracts in defining assigned responsibilities raise novel and significant questions of law that affect public interest and the administration of justice; leave was denied on the due diligence/foreseeability ground because the appeal judge correctly analysed that law and no injustice flowed from the trial judge's reasoning.

  • Directed verdict
  • Actus reus of statutory safety offences
  • Due diligence defence
  • Worker liability for workplace safety
  • Interpretation of s.28(1)(a) ohsa
  • Leave to appeal under provincial offences act s.131

Income tax act 2025 TCC 59

McCague v. The King

On the facts the appellant and Jones acted in concert and shared a common intent to extract corporate retained earnings by way of dividend while corporate tax arrears existed, so s.160 applies and the s.160 assessments are upheld; regarding 227 the T4s/T4 summary establish that amounts were deducted/withheld and thus were held in trust and the appellant, as a director, is jointly and severally liable under s.227.1 because he failed to exercise the required supervisory due diligence.

  • Section 160 income tax act
  • Non-arm's-length / acting in concert
  • Section 251(1)(c) factual test
  • Directors' liability s.227.1
  • Source deductions and t4s
  • Due diligence defence

Administrative law 2025 ONCA 329

Ontario (Labour, Immigration, Training and Skills Development) v. Greater Sudbury (City)

Leave to appeal was denied because the Crown failed to establish the high threshold for s.131 leave: the issues advanced were fact driven or mixed fact and law rather than pure questions of law, the POAC applied established legal principles (including the factors from Martin J. in Greater Sudbury) and there was no demonstrable legal error of sufficient public importance to justify this Court's intervention.

  • Due diligence defence
  • Control over workplace
  • Construction regulation compliance
  • Leave to appeal standards
