The Lord's Day Act, which since 1906 had prohibited business transactions from taking place on Sundays, was struck down as unconstitutional in the 1985 case R. v. Big M Drug Mart Ltd. Calgary police officers witnessed several transactions at the Big M Drug Mart, all of which occurred on a Sunday. Big M was charged with a violation of the Lord's Day Act. A provincial court ruled that the Lord's Day Act was unconstitutional, but the Crown proceeded to appeal all the way to the Supreme Court of Canada. In a unanimous 6-0 decision, the Lord's Day Act was ruled an infringement of the freedom of conscience and religion defined in section 2(a) of the Charter of Rights and Freedoms.
