Heritage statuses granted by the City of Saguenay

Arvida will thus become the thirteenth declared heritage site in all of Quebec.
Heritage site nominated
In June 2012, following the recommendation to that effect by the Historic Sites and Monuments Board of Canada, the Ministry of Environment has designated the National Historic Site of Arvida.
In January 2017, with the support of local communities along with its partners, the city of Saguenay has submitted the application of Arvida for Canada's tentative list for World Heritage Sites.
