Thank you very much for the question.
I agree because, in every other field of medicine, we have standards, either Canadian or international, for treating diabetes, Alzheimer's disease, obesity and heart disease. These standards must be based on the best scientific evidence available and, because Canada's provinces have relatively similar health care systems, it makes sense to bring the provinces together to benefit from their respective experiences and expertise.
It's also worth noting that Quebec's health services are accredited by Accreditation Canada, which also have national standards and has applied these standards in Quebec for decades. So, it's normal to rely on not only Canadian standards, but also international standards, to ensure Quebec and Canada have the highest possible standards in the world when caring for elderly people in institutions.
