The video shows an old, low-ceilinged basement, the dirt floor flooded with black and brown sludge. A broken cast-iron pipe is visible — the source of a leak spewing raw sewage into the basement of a home in New Glasgow, N.S., for about a year.

Tricia Gallant, 38, was living upstairs in one of the three rental units, experiencing nausea, dizzy spells, sinus infections and brain fog.

She had an inkling there was a problem, but didn’t realize her home was dangerous.

“When I moved into that place, I was living in my car,” Gallant said in an interview. “So I thought it was going to save me, when in reality it just made me sick.”

Gallant’s living conditions are an extreme example of how low-income tenants stuck in unfit housing can suffer physically and psychologically as they struggle to get repairs and keep a roof over their head. A recent CBC News investigation found renters living in dangerous, dilapidated housing are up against unresponsive landlords and a lack of protective bylaws.
