Legionella bacteria were discovered at high levels during routine testing on August 14 at Gatineau federal office building of Les Terrasses de la Chaudière. The potentially deadly bacteria were found in the heating, ventilation, and cooling system of the government building complex.
Bacteria levels exceeded the concentration of 100 colony forming units per milliliter (cfu/mL) set by Health Canada, but fell below the Quebec provincial reporting threshold of 1,000 cfu/mL.
According to Public Works and Government Services Canada, the water system was flushed and disinfected and follow-up testing showed that the bacteria levels are now within safe limits.
