Ontario long-term care providers won’t be applied retroactively for violations earlier in the pandemic when new legislation from the Progressive Conservatives takes effect, despite concerns that the worst offenders haven’t been held to account.The Ministry of Long-Term Care said it has not issued a single fine to operators who broke the rules during the COVID-19 pandemic, which has so far killed more than 4,000 people in long-term care and infected more than 15,000 nursing-home residents.The bulk of those deaths — which make up 40 per cent of all virus deaths in the province — occurred during the first two waves of the pandemic, before most residents in long-term care could be vaccinated.
