Should tax authorities be restricted from aggressive debt collection when it threatens active development projects?
In October 2026, real estate firms controlled by Terry Hui filed a Federal Court application to block the Canada Revenue Agency from collecting nearly $330 million in disputed tax debts. The companies allege the agency has engaged in a pattern of misconduct throughout an audit that began in 2013.
Why it matters
The outcome of this challenge could hinge on interpretations of Canada's tax treaty with Luxembourg, following a 2021 Supreme Court of Canada ruling that favoured taxpayers in a similar dispute. The companies contend that immediate payment of these debts would cause irreparable harm to their active development projects.
Adex Securities currently faces $45 million in tax debts plus $65 million in interest, while two Luxembourg-based shell companies owe a combined $92 million in taxes and $127 million in interest. The CRA has specifically requested a $115 million security payment from Adex.

This is the highest court in the country and previously set a relevant precedent regarding tax treaty disputes in 2021.
The details

This dispute illustrates the potential financial volatility for investors involved in companies that utilize international tax treaty structures. The outcome could set a standard for how taxpayers navigate future collection disputes with the federal agency.
The takeaway
Tax disputes involving international treaty structures can result in years of litigation and massive interest accruals. Businesses and investors should remain vigilant regarding changes in tax treaty interpretations and agency enforcement trends.
