The Due Diligence Defence & Directors’ Liability

Millar Kreklewetz
Explore more from Millar Kreklewetz

Directors of corporations that fail to remit GST/HST may face personal liability for unpaid taxes, but a due diligence defence exists. The recent Stevens v. The King case illustrates the high bar for proving due diligence, demonstrating that passive delegation of financial oversight is insufficient to avoid personal liability for directors.

The GST/HST framework under the Excise Tax Act (“ETA”), as with other indirect tax regimes (like federal and provincial alcohol, tobacco and vaping taxes) includes “directors’ liability” provisions that are triggered when the corporation does not have the money to pay an assessed amount. Most of these systems have “due diligence defences” and “statutory limitation rules” which may limit a director’s liability, but these rules are tricky to apply in practice.

We review these rules in a two-part series, with reference to the recent case Stevens v. The King, 2026 TCC 76 (“Stevens”), which revolves around this directors’ liability framework.

This Report concerns the “due diligence defence”. For our companion Report on “statutory limitations rules”, click here.

Cryptocurrency Held Through A Bare Trustee: Tax Treatment And The 2026 Reporting Obligations

If you hold cryptocurrency, NFTs or other blockchain assets in someone else’s wallet, or hold assets in your own wallet for someone else, the arrangement is very likely a bare trust. Until recently, that carried almost no compliance consequence. It now carries three reporting obligations to track: the T3 filing for 2026, the T1135, and the proposed Crypto-Asset Reporting Framework from 2027.

How To Appeal The Toronto Vacant Home (VHT) Tax: Here’s What One Landlord Did To Fight VHT Assessment

Since 2022, the City of Toronto has imposed an annual Vacant Home Tax (VHT) on residential units left unoccupied for more than six months of the year. For most owners the tax is an afterthought: file the annual declaration, confirm the unit was lived in, and move on. But when the City’s administrative process breaks down, an owner can find themselves fighting a five-figure tax bill over a unit they insist was never vacant at all.
