Six of Canada's ten provinces used to ban private insurance for publicly insured services to inhibit queue jumping and so preserve fairness in the health care system. In 2005, the Supreme Court of Canada ruled that in Quebec, such bans are unconstitutional if the waiting period for care is excessively long. However, this ruling only applies within the Province of Quebec. A second court challenge to determine whether the prohibition of private parallel health care violates the patients' right to life, liberty, and security under Section 7 of the Canadian Charter of Rights and Freedoms was defeated by the Supreme Court of British Columbia in 2020.
