Rand's decision required all workers to pay union dues, but protected the right of workers to not join the union or otherwise participate in sustaining it. In the late 1940s and 1950s, many Canadian provinces incorporated the "Rand formula" into their labor laws. By 1997, the federal government and six provinces (British Columbia, Manitoba, Newfoundland, Ontario, Quebec, and Saskatchewan) imposed the Rand formula on labor relations. Most of the laws provided for a religious exemption that imposed donation to a charity rather than union dues.
