The accused, a daycare provider, was charged with manslaughter after a 14-month-old child in her care died.
The Crown sought to admit several statements made by the accused to police officers.
The court found the accused was detained by the first responding officer without being advised of her rights, rendering subsequent statements to that officer inadmissible.
Statements made during a videotaped interview and a walk-through with a detective were found voluntary and admissible, except for a phone call to her husband which breached her right to privacy in seeking counsel.
Statements made to a third officer after the child's death were excluded as involuntary due to oppressive interrogation tactics, including ignoring repeated assertions of the right to silence, denying adequate warmth, and exploiting the accused's emotional distress.
