A fire in a third-floor apartment unit in Collingwood on Friday was electrical.
Fire Chief Ross Parr told Barrie 360 that two adult occupants and a County of Simcoe employee were taken to the hospital to be assessed for smoke inhalation.
Fire crews were called to the five-storey building on Second Street at High Street around 8:45 am.
The fire was contained to a single bedroom of the unit.
The damage is not considered extensive.
Parr confirmed the unit did have working smoke alarms.
