Following a fatal residential fire in Toronto, the Crown prosecuted the property owners for criminal negligence causing death, criminal negligence causing bodily harm, and mischief endangering life.
The Crown alleged the accused knowingly operated an unsafe rooming house in violation of Ontario Fire Code requirements despite repeated warnings and inspection notices from the Toronto Fire Service.
The court found that the property was in fact being operated as a rooming house rather than a single-family dwelling and that the landlord deliberately misrepresented the tenancy structure to avoid costly fire‑safety retrofits.
The failure to install required fire‑safety systems and to prevent cooking in bedrooms constituted a marked and substantial departure from the reasonable standard of care and was a significant contributing cause of the fatal fire.
One accused landlord was convicted of criminal negligence causing death, criminal negligence causing bodily harm, and multiple counts of mischief endangering life, while the co‑owner spouse was acquitted due to insufficient evidence of knowledge or participation.
