There were no reported injuries.
An investigation determined the fire began inside an exterior wall due to the electrical wiring being compromised and creating a heat source, which ignited surrounding building components.
According to the Saskatoon Fire Department, the exact cause for the failure of the electrical wire could not be established; however, there is no other heat sources where the fire started.
