A couple is homeless after fire gutted the main floor of their southwest Ottawa home Sunday morning.

Ottawa fire officials said they were called to 8300 Flewellyn Road at 7:30 a.m. Sunday after one of the homeowners reported smoke filling her basement.

Both people inside the home were out by the time crews arrived and started managing the fire, which they believe started in the basement.

They said the main floor was “extensively” damaged, with heavy smoke damage throughout.

It’s estimated to have caused $350,000 damage to the home and $75,000 to its contents.

Ottawa paramedics said they treated and took an 84-year-old woman to hospital for smoke inhalation.

Fire officials said the couple doesn’t need victims assistance because they have family in the area.

The cause remains under investigation.
