LRT service on the Eastern section of Line 1 remained offline this morning, as crews clean up Wednesday’s accident near Lees Station. An overhead power line was seen arcing during the early-afternoon commute before a small explosion caused the line to break. It’s not yet clear when all systems will be up and running again, but OC Transpo officials are crossing their fingers for a Friday restart. CFRA’s Andrew Pinsent delivers the latest developments in Hour 1. Meantime, The Ottawa Hospital is spearheading a groundbreaking international clinical trial in blood clot research. We dig deeper with Dr. Lana Castellucci, a Senior Scientist and Thrombosis Physician at The Ottawa Hospital. She is also the lead author of this trial. But first, we bring you up to speed on today’s top headlines.
