Not so much anymore. This is just anecdotal but I have noticed significantly less eh usage in the past decade than when I was a kid. I thought it was just a city thing. With Toronto being so diverse and having so many immigrants who would not have grown up with everyone saying eh all the time. But even when I moved out of the city to a town 2 years ago, I haven't really noticed any uptick in eh usage. I said eh to my wife last week and thought wow I haven't used eh in a non sarcastic form in a long time.
