The medical information due to the patient by the physician recognizes the importance of one’s personal autonomy in health care decision-making. While we can rejoice at this consecration, repairing the violation of patients’ rights when there is a lack of information remains very difficult in Quebec. The current medical civil liability mechanisms place a heavy burden on claimants. Despite these observations, Quebec civil law has not yet dwelled on proposing concrete solutions to overcome the difficulties raised by medical civil liability for lack of information. This text thus aims to discuss the issues presented by Quebec medical civil liability law with regard to the repair of the lack of information and to analyze solutions that could be implemented in order to overcome these pitfalls, by focusing more specifically on the injury of unpreparedness.
