The appellant was convicted of aggravated assault, administering a noxious substance, and failing to provide the necessaries of life in relation to her two-year-old son.
At trial, the Crown relied on expert evidence from the Motherisk Program regarding hair testing to prove the child had ingested cocaine over a 14-month period.
On appeal, the appellant sought to introduce fresh expert evidence challenging the methodology and validity of the hair testing.
The Court of Appeal admitted the fresh evidence, finding it credible and potentially decisive.
The convictions related to cocaine ingestion were quashed and a new trial was ordered, but the order was stayed because the appellant had already served her sentence.
The appeal from the fracture-related convictions was abandoned.
