In the course of ten years working for Metro Toronto Ambulance, I was into a least a few thousand homes, apartments, and flop houses, all over the largest city in Canada. Most of them were what I would describe as being " within normal conditions " BUT some were absolutely scary, in terms of the fire danger, or the very real chance of a collapse of the interior.
My partner and I were sent to a non emergency medical call at old house in the Cabbagetown area of the city. The elderly female occupant was at least 85 years old, lived alone, and had an estimated TWENTY cats in a tiny cottage style house. The Toronto Humane Society workers had managed to trap and cage the cats, so our job was to convince this woman to go to hospital, due to her terrible physical condition and illness.
She was lucid, and oriented as to place date and time, but she refused to acknowledge to squalor that she was living in. Conversation with her revealed that she had no living relatives . Eventually she was persuaded to go to the hospital for treatment and later she was placed in special city run home.
Her cottage was deemed "uninhabitable " by the Toronto Health Department, and it was demolished. She died and the city auctioned off the property to the public to cover the back property taxes that were owed on the house and land. JIM>
