In 1929, the government classified the first three historic monuments: the Maison des Jésuites-de-Sillery,[3] the Notre-Dame-des-Victoires Church[4] and the Château Ramezay.
[5] In 1935, the Legislative Assembly passed the Île d'Orléans Act to protect the traditional character of this cradle of settlement in the St. Lawrence Valley, threatened by the construction of a bridge.
This Act was replaced by the Loi des monuments historiques, introduced by the Minister of Cultural Affairs, Georges-Émile Lapalme.
The Cultural Property Act, assented to on July 8, 1972, was a major step forward in the protection of Quebec's heritage.
[10] The granting of certain legal status under the Cultural Heritage Act has a number of effects with regard to works and disposals.
