In a class action arising from a COVID-19 outbreak at a long-term care home, the appellants challenged certification of causation and punitive, exemplary or aggravated damages as common issues, and sought leave to appeal the certification costs award.

The Court of Appeal held that the motion judge properly found some basis in fact for a workable methodology for proving causation on a class-wide basis through a risk ratio approach supported by available data and expert evidence.

The court also upheld certification of punitive, exemplary or aggravated damages, rejecting the argument that such relief could not be certified absent common compensatory damages, noting that sequencing could address any quantification concerns.

Leave to appeal costs was denied because no strong grounds were shown for appellate intervention in the discretionary costs ruling.

The defendant radiologist moved for summary judgment dismissing the medical malpractice claim against him, arguing the plaintiffs failed to tender expert opinion evidence on causation.

The plaintiffs cross-moved for leave to admit late-served expert reports from a gastroenterologist and a radiologist.

The court granted the plaintiffs leave to admit the late reports, finding that their exclusion could cause a miscarriage of justice and the defendants would not suffer undue prejudice given the trial's adjournment.

Relying on the newly admitted expert evidence regarding standard of care and breach, the court dismissed the defendant's summary judgment motion, concluding that a genuine issue requiring a trial existed and that an inference of causation might be drawn at trial.

The issue of costs thrown away due to the trial's adjournment was reserved to the trial judge.
