  • Crump v. Fiture

  • Sims v. Zaitlen

    On October 2006, Maddalena Sims presented at the William Osler Health Center in Brampton with a complaint of a sudden onset of headache pain.

    On December 2012, she was ultimately diagnosed with varicella zoster encephalitis (VZV).

    The plaintiffs assert that the defendant doctors were negligent in the delayed diagnosis of VZV, which resulted in the delayed treatment with the antiviral medication, all of which resulted in a worse outcome than would have otherwise occurred with an earlier diagnosis and treatment.

    Sims v. Zaitlen, 2017 ONSC 2501 – Endorsement

  • Barber v. Humber River Regional Hospital

    Mark Barber died on February 17, 2006, at Humber River Regional Hospital in Toronto from pneumococcal bacterial meningitis. He was 46 years of age. The respondents, his surviving wife and two daughters, sued two emergency room physicians, the appellant Dr. Virat Joshi, and Dr. David John Shergold, in negligence, alleging that Mr. Barber’s death resulted from their failure to properly investigate, diagnose and treat his meningitis.

    Responding to Dr. Joshi’s appeal to the original Judgement by Justice Mary A. Sanderson:

  • Fine v. Botelho

    Fine v. Botelho; 2015 ONSC 6284 – Reasons for Decision (Plaintiff’s motion to consolidate)

  • Shearer v. Sewchand

    The honourable Judge H.K. O’Connell, J. noted: The minor plaintiff, S. Shearer was significantly affected by the doctor’s negligence. Not only was Stone the recipient of hearing loss due to the negligence, he required hospitalization, surgery, rehabilitation, and ongoing therapy. He also required ongoing therapy to address his facial paralysis, wrought by Dr. Sewchand’s negligence.

    The Plaintiffs argue that the doctor vigorously defended that case in the face of overwhelming evidence against him. His refusal to settle, or even to engage in settlement discussions, “was the sole reason for this trial.”

    Shearer v. Sewchand, 2013 ONSC 4052 – Judgment

    Shearer v. Sewchand, 2013 ONSC 6760 – Endorsement of Costs

  • Costantini v. Wong, Sanders, McRitchie

    2009 ONSC 51196 (CanLII) – Decision

  • Itamunoala v. Peirce
