The plaintiff sued an imaging clinic and a radiologist for medical negligence, alleging a failure to diagnose breast cancer from mammograms and ultrasounds conducted in 2008 and 2009.

The court found no evidence that the clinic's imaging fell below the standard of care, noting that the plaintiff's dense breast tissue made imaging difficult but diagnostic.

The court also dismissed the claim against the radiologist, finding that his interpretation of the imaging was a reasonable exercise of clinical judgment and that he could not be judged retrospectively with the benefit of hindsight.

The action was dismissed.

The plaintiffs brought a motion to certify a class action against several manufacturers of lithium-ion batteries, alleging a price-fixing conspiracy that artificially inflated prices for direct and indirect purchasers in Canada.

The court certified the action solely for the statutory cause of action under section 36 of the Competition Act.

The court excluded 'umbrella purchasers' (those who bought from non-defendants) from the class, finding it plain and obvious they lacked a cause of action due to indeterminate liability and lack of restitutionary basis.

The court also declined to certify the common law claims for unlawful means conspiracy and unjust enrichment, holding that they were precluded by the comprehensive statutory scheme of the Competition Act.

The remaining certification criteria were met for the statutory claim.
