The Franco-Ontarian flag 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 color on the flag is Pantone 349, in RGB (0,99,56).
The flag was created in 1975 by Gaétan Gervais, history professor and Michel Dupuis, first year political science student, both from Laurentian University. It was officially recognized as the emblem of the Franco-Ontarian community in the Franco-Ontarian Emblem Act of 2001.
Ironically, in 2003 a controversy arose in Sudbury when the city government voted against flying the flag at Tom Davies Square for St-Jean-Baptiste Day, claiming that it would be inappropriate for the city government to display on public property a symbol representative of only a portion of the city's population. In 2006, new mayor John Rodriguez reversed that decision, permitting the flag to be flown, but was again criticized by some voters for acting unilaterally.
To commemorate the 30th anniversary of the Franco-Ontarian flag in September 2005, Prise de parole, a Sudbury-based publishing house, published a book titled Le Drapeau franco-ontarien (edited by Guy Gaudreau, a history professor at Laurentian University.)
On September 25, 2006, the largest Franco-Ontarian flag was unfurled in Ottawa. The historical park, also known as Les Monuments de la francophonie d'Ottawa, was built by the francophone community to commemorate francophone contribution in the development and well being of the City of Ottawa. This first of six Monuments de la francophonie d'Ottawa is dedicated to the subject of education. The flag is 5 x 10 m and was raised on a 27 m pole.
