Courts in BC have assigned up to what percentage of the blame to establishments that allow patrons to drink and drive resulting in injury or death to other citizens?

In British Columbia, courts have assigned up to 100% of the blame to establishments that serve alcohol to patrons who subsequently drive and cause injury or death to others. This reflects the legal principle of "dram shop liability," which holds bars and restaurants accountable for overserving intoxicated individuals. Establishments can face significant legal consequences if found negligent in their service practices.
