Flag represents the two flowers of what I am - french and ontarian
Colours represent summer (green) - hope, celebrating our growth, survival, in spite of the realities of being overwhelmed by anglos
White represents our winters - and the sheer blank lack of understanding extended by non francophones in this province. Our history is strife with attempts to 'exterminate' or assimilate us. We finally got funding for french high schools just at the time when I was reaching high school. 5 years before I graduated, less than 10% of francophones had completed their high school education, while the average for the province was over 50%. Even in heavily 'french' populated parts of the province, nearly all teachers were french, nearly all students were french, but the language of education was english!
And the battle still continues. About 15 years ago we finally got french colleges in this province (some classes were being taught in french, but the colleges were english). And we still haven't, to this day, got our own french university in Ontatrio - not one! Sure there's the universtity of Ottawa & the Sudbury university (Laurentienne), but they teach some classes in french and some in english. In the 70's, when I went to Ottawa U., about 40% of the student body was french, as were about 75% of my classes.
As little as 7 years ago, the much hated conservative government of Ontario, in an attempt to reduce health cost, closed a bunch of hospitals (including one that usta be a walking distance from my house). Among the planned closures was the ONLY french speaking educational hospital west of Québec. The battle to keep Montfort open is quite a moving episode in our history, and thanks to the courts and the charter of rights (which has also been catalistic in allowing gay mariages in Canada), the hospital Montfort is still a thriving institute today.
The significance of the white on the flag is important, cause non-francos just don't have a clue! Their awareness is truly blank-like.
