Three family pets are missing and presumed dead after a house fire south of Saskatoon.
Dispatchers were told everyone inside the home had escaped, but a dog and two cats were trapped inside.
Firefighter said heavy smoke and flame was coming from the home when they arrived.
A defensive attack was started to control and prevent the fire from spreading, fire officials said, and a collapse zone was established around a half-full tank of diesel.
Water tankers were used to shuttle water to the fire scene.
Additional crews were brought in so firefighters could rotate out due to extremely cold conditions and monitor for hot spots.
Fire officials said arrangements have been made with a local animal care facility to find temporary shelter for another dog that was able to escape.
The Saskatoon Fire Department said it will not release a fire cause or damage estimate as the incident is outside its jurisdiction.
