Immigration: Quelling the conflict between French and English Canada?

At the annual Canadian Association of Principal’s Conference, currently being held in St. John’s, Newfoundland and Labrador, keynote speaker Gwynne Dyer said:

“…federal immigration reforms since the 1960s have changed demographics in a way that is largely responsible for quelling the conflict between French and English Canada. It has essentially…saved this country as a political entity. These policies have resulted in classrooms in large urban centres with children with diverse culturally backgrounds, creating challenges for Canadian educators….It’s been a journey that’s occurred with remarkably little conflict.  This is an extraordinary accomplishment, which you might want to bare in mind next time you deal with the downside”.

What do you say, educators? Is Gwynne right?
