Calgary police confirm that two people are dead after officers were called out early Tuesday morning to reports of two people in medical distress in the northeast community of Rundle.
Police say the call came in shortly before 1:30 a.m. to the 900 block of Rundlecairn Way, N.E.
When officers arrived, they discovered two people in a detached garage, who were removed to a nearby alley.
Despite CPR efforts by Calgary firefighters, one person was declared deceased on scene, while the second person was transported to hospital, where they later died.
The Calgary Fire Department (CFD) said testing by firefighters detected carbon monoxide levels of 300 parts per million inside the garage.

While a CFD spokesperson could not confirm that CO poisoning was the cause of death, Calgary police said the deaths are believed to be non-criminal in nature.
Carbon monoxide is described by Health Canada as an odourless, colourless and tasteless gas that is dangerous to human health because breathing it in reduces the blood’s ability to carry oxygen.
It is created by the burning of fuels such as propane, natural gas, gasoline, oil, coal and wood, and can only be detected with a carbon monoxide alarm (commonly known as a CO detector).
Symptoms from extended exposure at low levels include headaches, shortness of breath an difficulty walking.
Exposure at higher levels include chest pain, poor vision and difficulty thinking and at very high levels it can cause convulsions, coma and even death.
