The Franco-Ontarian flag is a symbol created to represent Franco-Ontarians, reflecting the diverse languages, seasons and people of Ontario. The design consists of two bands of green and white. The left portion has a solid light green background with a white fleur-de-lys in the middle, while the right portion has a solid white background with a stylized green trillium in the middle.
The green represents the summer months, while the white represents the winter months. The trillium is the floral symbol of Ontario, while the fleur-de-lys represents the French Canadian heritage of the Franco-Ontarian community. The green colour on the flag is Pantone 349, in RGB (0,99,56).
