The reason there are staffing issues at least in the public LTC of Quebec and Ontario is mainly funding related. The issues uncovered in the "chain" of LTC in Quebec was funding, greed and mismanagement.
In the case of the the private chain "Heron" (the one where families were paying 10k and more per month for their relatives to stay there). The Owners where residents were abandoned and 47 of them died, settled quickly last month the civil suit brought by some families of the dead residents for $5.5 million dollars. The Judge approved of the settlement 4 days ago.
Meanwhile the investigations led by the Coroner's Office of Quebec are ongoing and expected to be completed in the fall of 2021 but so far for the most part while the Coroner's conclusions are obvious that the residents died of neglect he commended staff for fighting in what became inhumane working conditions with no protection due to a failure of government acting quickly enough to realize that this was a National Health Emergency. Some other recommendations are being made such as the elimination of multiple residents sharing rooms, which appears will become unlawful and other measures.
Bottom line the government will have to face the fact that more financial, training and logistic resources need to be made...
