Here is a link that explains more in detail what the bill 20 consists of: http://globalnews.ca/news/1728556/opinion-bill-20-will-turn-every-patient-in-quebec-into-a-number-instead-of-a-person/
Briefly, though, this bill will establish a quota of patients/hours of work in hospitals/days worked per year.
If you consider it, it doesn't seem that bad, but the doctors are trying to victimize themselves, by using the patients as argument or other arguments against this bill(as if the patients will be transformed in numbers, and so on).
I would like to see if there are any similar laws, in other countries or provinces. Are there quotas? And if so, what are they? In general the article is written more from a humanistic style than a documented one (with data and charts).
