Hi Frenchy,
I live in Montréal and especially when I go out in the west of Montréal, it's now rare when we are served in french, even native french speaker start with english. I believe because of a fall of the birth rate especially in french canadians and with an increase of immigration, the animosity is more about religions such as between jews and muslims and since 911 I think racism has increased. So yes the animosity between the têtes carrées and the frogs was more virulent like 20 years ago. Now with the internet and everything, it's in the interest of young french canadians to learn english. There are still some die hard separatist who blame everything on the english and the americans but they are a minority and shouldn't be taken very seriously.
