Police are investigating after a mother and two children were rescued from a house fire in Bonython on Sunday morning.
It was one of three structural fires overnight.
The ACT Emergency Services Agency said firefighters found the home on Bardolph Street, Bonython, alight when they arrived just before 6.30am.
"Firefighters in breathing apparatus entered the structure and conducted fire suppression and search operations," they said in a statement.
"Firefighters located a woman and two children and rescued them from the structure."
Neighbours told The Canberra Times a single mother and her two children lived in the home and had lived at the address for a number of years.
Police were still at the scene of the fire for much of the morning and roadblocks were in effect for parts of the street. Several windows on the outside of the home had been shattered due to the fire.
An ACT police spokesman said an investigation had been launched into the cause of the fire.
Firefighters, paramedics and police conducted CPR and oxygen resuscitation on the three people, who have been taken to hospital.
It was a busy day for Canberra firefighters, with the fire at the Bonython home being one of three separate blazes at Canberra properties on Sunday.
Earlier, firefighters were called to an inferno at a shed in Hayter Place in Page.
The fire started at 1am, with crews having to rescue two dogs from the shed.
Crews worked to contain the blaze to prevent it spreading to a nearby home.
The fire was put out around 2am, with the dogs being reported as safe.
Emergency crews stayed on the scene for several hours to ensure the area was safe.
Just after 2pm, fire crews were called to a home on Bird Place in Flynn, after solar panels on the roof caught alight. The residents were able to get out of the home safely before firefighters arrived.
The fire was extinguished just before 3pm.
Emergency crews have urged Canberrans to be safe around the home during the colder months to prevent house fires, with more than a quarter of the 250 house fires responded to every year happening in winter.
