Following judgment awarding damages for auditor negligence, the court determined the appropriate prejudgment interest rate and start date under the Courts of Justice Act.

The court rejected the plaintiff’s proposed interpretation of the Ministry interest rate tables and held that the statutory quarterly rate corresponding to the commencement of the action applied.

The court also declined to average interest rates over the period absent compelling justification, emphasizing that deviations from the statutory scheme require substantial evidence.

Applying ss. 128 and 130 of the Act, the court structured the accrual of prejudgment interest to reflect when losses were actually incurred rather than the breach date alone.

Interest was calculated in stages culminating in a total prejudgment interest award exceeding $33 million.

Livent Inc., through its Special Receiver, sued its former auditors, Deloitte & Touche, for negligence and breach of contract in failing to detect massive corporate fraud perpetrated by Livent's directing minds, Garth Drabinsky and Myron Gottlieb.

The court found that Deloitte failed to conduct its 1996 and 1997 audits in accordance with generally accepted auditing standards (GAAS), particularly regarding preproduction costs and complex revenue transactions.

The court rejected Deloitte's defences based on the corporate identification doctrine and ex turpi causa, holding that the fraud of the directing minds could not be attributed to the company to shield the negligent auditors.

Damages were assessed at $84,750,000, representing the increase in Livent's liquidation deficit caused by the delayed discovery of the fraud, discounted by 25% for business contingencies.
