A fire in a seven-storey apartment building on Barton Street East forced tenants to evacuate the building and wait in HSR buses around 7:30 Thursday evening.

Hamilton Fire crews extinguished the fire quickly and worked to clear the building of smoke. They contained the fire to one unit. Damage was estimated at $100,000, according to Hamilton Fire spokesman Claudio Mostacci. 

The Ontario Fire Marshal has been asked to investigate the fire's cause. Hamilton Fire recommends tenants in apartment buildings review the posted emergency information in their buildings.
