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?
