Lavergne Law

The La Vergne Law (or Lavergne Law) of 1910, formally known as the Loi amendant le Code civil concernant les contrats faits avec les compagnies de services d'utilité publique (1910, Geo. V, c. 40), was an act of the Parliament of Quebec which made the use of both English and French mandatory on tickets, documents, bills and contracts issued by transportation and public utility companies. Prior to this, these were customarily in English only.

The law's primary sponsor was Armand La Vergne (or Lavergne), a legislator representing the Ligue nationaliste canadienne. The law came into effect on January 1, 1911.

Although the scope of the legislation was very limited, it is remembered today as the first example of French-language rights legislation in Quebec.
