The "Lord's Day Act", which since 1906 had prohibited business transactions from taking place on Sundays, was declared 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.
