  1. Regarding Kara’s question. One issue as to why Ontario’s health care system may be overwhelmed is because we have “free” healthcare and people go to hospital emergency departments for ANYTHING. So people with minor infections with minor symptoms will still go to the emergency ward for conditions that do not require emergency ward attention.. Also Ontario’s hospitals, especially in Toronto are severely understaffed now due to the wholly incompetent, somewhat Trumpian, Conservative government response, exacerbated by a profit driven Unity Health corporate style management policy, which emphasizes billing the tax payer for every hospital admission, necessary from a healthcare perspective or not, which has abused front care workers, especially nurses, to the point there are only 30% of required staff available in some of the major hospital emergency and ICU departments due to burnout and illness. It’s a scandal that is under reported here.
