The damage is estimated at about $300,000 after crews responded to a kitchen fire in Port Colborne.
Crews were called to a townhouse complex on Wellington Road early yesterday evening.
The fire spread to neighbouring units, but everyone was able to evacuate safely.
Two firefighters had to be taken to hospital afterward, where they were treated for heat exhaustion and minor injuries related to a ceiling collapse.
They were both released last night.
