Montreal – A St. Michel High School and its business school will remain closed on Monday, in anticipation of results of tests after the discovery of airborne asbestos fibers. John F Kennedy School was closed last Thursday and Friday as well. An asbestos abatement company removed traces of asbestos discovered in 2 ventilation rooms approximately three weeks back, according to the English Montreal School Board (EMSB). Some air quality tests conducted in the rooms indicated the rooms are safe. However, additional precautionary tests in the other portions of the building showed traces of asbestos. Latest update will be provided by the EMSB on Monday.
