The sprinkler system quickly doused a fire at the Minto Suite Hotel Friday morning after a night that kept firefighters busy with two east-end house fires including one that sent three people to hospital with smoke inhalation.

The fire department was called to 185 Lyon Street North at 8:15 a.m. as residents were brought to the building’s lobby. The smoke and water was limited to a unit under renovation and an adjacent unit. Fire crews were clearing the scene within the hour.
