The Quebec government has ordered a public inquiry into an outbreak of legionnaires' disease that has killed nine people.
Thursday's announcement came hours before public health officials announced the number of overall cases of the disease in Quebec City had jumped to 151 from 141.
Cooling systems in two building towers are believed to be the source of the current outbreak. Local authorities have disinfected the cooling systems in more than 100 buildings.
Inspectors are revisiting about 30 of them to look at the water and to make sure building owners have complied with clean-up directives.
Solange Allen, whose husband, Claude Desjardins, died of the illness on Aug. 19 held a news conference on Thursday with her lawyer, with whom she has discussed the possibility of a class-action lawsuit.
