The plaintiffs sued Ontario in negligence, alleging the province failed to prevent the outbreak of West Nile Virus in 2002, resulting in the deceased contracting the virus and dying from complications.
Ontario moved to strike the statement of claim for disclosing no reasonable cause of action.
The motions judge and Divisional Court dismissed the motion.
On appeal, the Court of Appeal allowed the appeal and struck the claim, holding that the Health Protection and Promotion Act imposes a general public law duty to protect health, but does not create a private law duty of care owed to specific individuals to prevent the spread of infectious diseases.
