“QC” – Queen’s Counsel is a defunct designation once given to lawyers in Ontario who had shown they were “learned in the law.” Roughly equivalent to “senior counsel,” the “QC” honourific was discontinued in 1985. Those already named QC may continue to use it, but many choose not to.
No federal Queen’s Counsel have been named since 1993. Several provinces continue the practice. In British Columbia, a panel recommends Queen’s Counsels to Attorneys General, who, if they are lawyers, are automatically appointed QCs.
