In a voir dire during a trial, the plaintiffs challenged the qualification of the defendants' proposed expert witness, a forensic psychiatrist, arguing that a previously undisclosed 2002 draft report demonstrated a lack of independence.

The plaintiffs alleged that the expert's subsequent 2003 and 2019 reports were substantively altered to align with the defendants' legal position.

The court held that while the differences between the reports raised a suspicion sufficient to lift any litigation privilege over the draft report, they did not warrant disqualifying the expert at the threshold stage.

The expert was qualified to testify, with the draft report permitted to be used for cross-examination, and the ultimate assessment of his credibility and independence reserved for the trial judgment.

In a voir dire during a trial regarding historical programs at a psychiatric facility, the plaintiffs challenged the qualification of the defendants' proposed expert witness, Dr. Turrall.

The plaintiffs argued he lacked credibility because substantial portions of his report on the standard of care were copied verbatim from another expert's memo.

The court found the standard of care portion of the report unnecessary and excluded it, but qualified the expert to testify on causation issues regarding specific plaintiffs, as that portion of his report was based on his own review of medical records.

The plaintiffs brought a mid-trial motion to disqualify the defendants' proposed expert witness, Dr. Vernon Quinsey, arguing he lacked the requisite independence and objectivity.

Dr. Quinsey was previously employed as a staff psychologist and Director of Research at the very psychiatric facility whose programs were being challenged as unethical human experimentation.

The court found that Dr. Quinsey's integral role in evaluating the contentious programs during the relevant period created a serious doubt as to his objectivity.

The court concluded that the prejudicial effect of his evidence outweighed its probative value, and disqualified him from testifying as an expert, though permitting him to testify as a fact witness.

The plaintiff pension fund sought leave under s. 138.8 of the Securities Act to commence a $3 billion secondary market securities class action against the defendant mining company.

The plaintiff alleged misrepresentations in three categories: capital expenditure and scheduling, environmental compliance, and accounting and financial reporting.

The court dismissed the motion for leave regarding the capital expenditure and accounting allegations, finding that the plaintiff failed to satisfy the public correction requirement.

However, the court granted leave to proceed with one core environmental allegation, finding a reasonable possibility that the plaintiff could establish at trial that the defendant's July 26, 2012 representation about the completion of a water management system was an untrue statement of material fact.

The defendants brought a mid-trial motion to admit three sur-reply expert reports.

The plaintiffs opposed, arguing the reports were unnecessary, prejudicial, and served late.

The court admitted two of the reports, finding them to be narrowly tailored responses to specific criticisms raised by the plaintiffs' experts.

However, the court excluded the third report, finding it to be an advocacy piece that improperly introduced new evidence and amounted to case-splitting.

The defendants brought a mid-trial motion to exclude video footage of an interview between a deceased plaintiff and a documentary filmmaker.

The plaintiffs sought to introduce the unsworn footage to demonstrate the deceased plaintiff's sincerity and counter credibility attacks in the defendants' expert reports.

The court held that the video footage did not meet the criteria of necessity and reliability under the principled approach to hearsay, noting that the best available evidence was the deceased plaintiff's sworn examination for discovery transcript and affidavit.

The motion to exclude the evidence was granted.

At a pre-trial conference for a six-week trial, the court provided procedural directions regarding the presentation of evidence.

The court permitted the plaintiffs to use affidavits for their evidence-in-chief to save time, but declined to admit discovery transcripts en masse.

The court also agreed with the defendant that the judge should not read the expert reports until after hearing the plaintiffs' viva voce evidence, to avoid being influenced by the experts' interpretation of the plaintiffs' testimony before hearing it firsthand.

The parties appeared before the court to advise that the contested issue of carriage had been resolved by consent.

The court approved an agreed-upon schedule for the proceedings leading up to a certification motion and potential jurisdiction motions, including deadlines for the production of medical and gambling records, delivery of materials, cross-examinations, and factums.

The plaintiffs sought leave under s. 138.3 of the Securities Act and certification under the Class Proceedings Act to pursue a class action against CIBC and its senior officers for alleged secondary market misrepresentations concerning CIBC's exposure to the U.S. residential mortgage market.

The court found that the plaintiffs met the test for leave and certification for the statutory claim.

However, applying the Court of Appeal's recent decision in Sharma v. Timminco Limited, the court held that the statutory claim was time-barred because leave was not obtained within the three-year limitation period under s. 138.14 of the Securities Act.

Consequently, both motions were dismissed.
