The Saskatoon Fire Department is reminding people to watch where they butt out after fire broke out at a condominium Sunday.
Around 12:45 p.m., crews were called to a fire in the 300 block of Zary Road in northeast Saskatoon.
Fire officials said they found heavy smoke and flames coming through the back of the residence.
Three adults left the home before crews arrived, and no other people were found in nearby condos.
Crews had the fire under control in 37 minutes and no one was injured.
A fire investigator was called to the scene and found the blaze was caused accidentally by smoking materials.
No other information was provided on this, except a warning from the fire department urging people not to dispose of smoke materials in planters containing highly flammable peat moss.
Damage from the fire is estimated to be $400,000.
