The house was classified in 1977 by the Quebec government and was granted a protection area in 1979 (link in French). Pierre Thibault, the penultimate owner, restored this heritage house to its former glory; unfortunately, the house has been in constant disrepair since his death.
The current owner, who acquired the house in 2008, filed a demolition application with the City of Laval in 2014, which was rejected. However, no restoration and protection work was undertaken, which precipitated the building’s deterioration.
According to Jean-François Nadeau of Le Devoir in a November 29, 2018 article (in French), “the Ministry does not intend to require a complete renovation of the building, but rather work that would preserve its heritage values and slow its deterioration, so minimally the consolidation of the structure. In principle, the law [on cultural heritage] allows the State to intervene to protect a heritage property under its responsibility. In this case, as in others, the Ministry prefers to continue hoping that the owner will eventually agree with its arguments.”
However, in 2019, the Ministère de la Culture et des Communications obtained an order from the Superior Court “that will allow it to proceed itself with the protection work of the Charbonneau House in Laval, neglected by its owner,” according to Jeanne Corriveau of Le Devoir in a November 27, 2019 article (in French); a rare phenomenon, but one that was hailed by the heritage community. Despite this order, a follow-up is still necessary so that the work can be completed and the Charbonneau house can regain its original luster.
