The flag of which Canadian province features four fleurs-de-lis flowers?

The flag of Quebec, called the Fleurdelisé, was adopted for the province by the government of Quebec, during the administration of Maurice Duplessis. It was the first provincial flag officially adopted in Canada, first shown on January 21, 1948, at the Parliament Building of the National Assembly in Quebec City.

The Fleurdelisé takes its white cross from the ancient royal flags of France.

Its white fleurs-de-lis (symbols of purity) and blue field (symbolizing Heaven) come from a banner honouring the Virgin Mary. One such was reputedly carried by French Canadian militia at General Louis-Joseph de Montcalm's victory at Carillon.

The fleur-de-lis or flower-de-luce is a stylized lily (in French, fleur means "flower", and lis means "lily") that is used as a decorative design or symbol.

The flag is blazoned Azure, a cross between four fleurs-de-lis argent. Its horizontal symmetry allows both sides of the flag to show the same image.
