The Liberal Party announced Saturday afternoon that family physician Dr. Danielle Martin will be their candidate for the upcoming federal byelection in University-Rosedale, the downtown Toronto riding Chrystia Freeland held until she stepped down earlier this month. Martin is the chair of the department of family and community medicine at the University of Toronto. In 2014, she defended Canada's health care system before a partisan U.S. Senate committee an act that received widespread attention at the time.
