The accused, a paternal grandfather, was charged with manslaughter in the death of a 13-month-old child in his care.
The child suffered a fatal traumatic brain injury while under the accused's supervision.
The Crown alleged the accused violently shook the child and impacted the child's head against a hard surface.
The defence contended the child's injuries resulted from an accidental collision with a large family dog.
The court found the accused guilty of manslaughter, rejecting the defence theory as internally inconsistent, medically implausible, and unsupported by credible evidence.
The court determined the accused assaulted the child through violent shaking, which constituted the unlawful act causing death.
