Investigators alongside a Hazardous Materials team had to shut down part of Rideau Street just east of Elgin after reports of a possible chemical scare.
Police would only say they are investigating an incident but were thin on details.
Reportedly, a bus driver had to be treated after a possible reaction to an undisclosed substance. CTV also heard that two paramedics were assessed after potential exposure.http://ottawa.ctvnews.ca/oc-transpo-chemical-scare-closes-roads-near-national-war-memorial-1.3614226
