The Ontario government says it plans to join British Columbia’s proposed class action lawsuit against dozens of opioid manufacturers. Attorney General Caroline Mulroney says the province will introduce legislation that, if passed, would enable Ontario’s participation in the suit launched late last year. Ontario also says it will establish an agency to oversee mental health and addictions care across the province. Mulroney says the current system is fragmented and confusing for patients and their families. She says the Mental Health and Addictions Centre of Excellence will be a central point for oversight of care.
