How a Sikh lawyer forced Canada to drop century-old oath to monarch

Prabhjot Singh Wirring, a Sikh lawyer from Punjab, successfully challenged Canada's mandatory oath of allegiance to the British monarch for professionals. The Alberta Court of Appeal ruled the oath violated religious freedom, ending a century-old requirement for lawyers and other professionals. The decision is seen as a major constitutional shift in Canada, benefiting others who objected to the oath on religious or personal grounds.
