Ottawa fire officials said they were called to the complex at 2949 Penny Drive, located just west of the intersection of Richmond and Carling roads, before 7:30 p.m.

When they arrived, firefighters reported smoke and flames coming from all three floors of Unit 35 and quickly upgraded to a second alarm.

Neighbours said they saw the woman who lived in the townhouse run back inside to get her dog and neither came back out.

Fire officials confirmed to CBC News a woman and dog were both killed.

Most of the fire was out by 8:20 p.m. and it was under control less than 10 minutes later, but not before flames spread to another nearby unit.

A firefighter also suffered a minor foot injury, according to a news release.

Damage is estimated at $500,000 to the building and contents. The cause is under investigation.
