Tax Litigation

  • In American Income Life Insurance v. The Queen, 2008 TCC 306, BLG argued successfully that a U.S. insurance company was not subject to tax on its Canadian business profits because it did not have a permanent establishment in Canada, within the meaning of the Canada-U.S. tax treaty
  • In Birchcliff Energy Ltd. v. The Queen, 2012-1087(IT)G, the BLG team successfully compelled the Crown to provide greater disclosure in the pleadings involving the general anti-avoidance rule in the Income Tax Act, changing the law and significantly increasing the disclosure obligation of the government when it accuses taxpayers of “abusive” tax planning
  • In Ollenberger v. The Queen, 2013 FCA 74, we successfully established that a start-up oil and gas company was carrying on an "active business" such that the taxpayer was entitled to a favourable tax treatment for an investment loss.  This was an important precedent regarding the fundamental concept of when a business commences for tax purposes
