The Saskatoon Fire Department said crews brought the blaze under control at 8:46 p.m., noting that nobody was injured.
An investigation into the fire found that it started inside a pillar that was supporting the roof over the front door.
A paper cup for cigarette butts was near the pillar, and butts were found in the pillar as well.
